Remove gnuwin32 - it is provided through provisioning

Having a few windows specific tools in qt5.git was always strange. We
now provision the utilities to the machines, so remove them from
qt5.git.

[ChangeLog][General] GnuWin32 is no longer part of the Qt source code repositories.
Instead it can be downloaded from the upstream project at https://gnuwin32.sourceforge.net .
For convenience we also make a copy available here:
https://download.qt.io/development_releases/gnuwin32/gnuwin32.zip
The GnuWin32 tools are needed for building Qt from source on Windows.
Binary package downloads are not affected.

-NAME
-       iconv - perform character set conversion
-
-SYNOPSIS
-       #include <iconv.h>
-
-       size_t iconv (iconv_t cd,
-                     const char* * inbuf, size_t * inbytesleft,
-                     char* * outbuf, size_t * outbytesleft);
-
-DESCRIPTION
-       The  argument cd must be a conversion descriptor created
-       using the function iconv_open.
-
-       The main case is when inbuf is not NULL  and  *inbuf  is
-       not NULL.  In this case, the iconv function converts the
-       multibyte sequence starting at  *inbuf  to  a  multibyte
-       sequence  starting  at  *outbuf.   At  most *inbytesleft
-       bytes, starting at *inbuf, will be read.  At most  *out-
-       bytesleft bytes, starting at *outbuf, will be written.
-
-       The iconv function converts one multibyte character at a
-       time, and for each character  conversion  it  increments
-       *inbuf and decrements *inbytesleft by the number of con-
-       verted input bytes, it increments *outbuf and decrements
-       *outbytesleft  by  the number of converted output bytes,
-       and it updates the conversion  state  contained  in  cd.
-       The conversion can stop for four reasons:
-
-       1.  An  invalid multibyte sequence is encountered in the
-       input. In this case it sets errno to EILSEQ and  returns
-       (size_t)(-1).  *inbuf  is left pointing to the beginning
-       of the invalid multibyte sequence.
-
-       2. The input byte sequence has been entirely  converted,
-       i.e. *inbytesleft has gone down to 0. In this case iconv
-       returns the number of  non-reversible  conversions  per-
-       formed during this call.
-
-       3.  An  incomplete  multibyte sequence is encountered in
-       the input, and the input byte sequence terminates  after
-       it.  In  this  case  it sets errno to EINVAL and returns
-       (size_t)(-1). *inbuf is left pointing to  the  beginning
-       of the incomplete multibyte sequence.
-
-       4.  The output buffer has no more room for the next con-
-       verted character. In this case it sets  errno  to  E2BIG
-       and returns (size_t)(-1).
-
-       A  different  case  is  when  inbuf is NULL or *inbuf is
-       NULL, but outbuf is not NULL and *outbuf is not NULL. In
-       this  case, the iconv function attempts to set cd's con-
-       version state to the initial state and  store  a  corre-
-       sponding  shift  sequence  at  *outbuf.   At  most *out-
-       bytesleft bytes, starting at *outbuf, will  be  written.
-       If  the  output  buffer  has no more room for this reset
-       sequence,  it  sets   errno   to   E2BIG   and   returns
-       (size_t)(-1). Otherwise it increments *outbuf and decre-
-       ments *outbytesleft by the number of bytes written.
-
-       A third case is when inbuf is NULL or  *inbuf  is  NULL,
-       and outbuf is NULL or *outbuf is NULL. In this case, the
-       iconv function sets cd's conversion state to the initial
-       state.
-
-RETURN VALUE
-       The iconv function returns the number of characters con-
-       verted  in  a  non-reversible  way  during  this   call;
-       reversible  conversions  are  not  counted.   In case of
-       error, it sets errno and returns (size_t)(-1).
-
-ERRORS
-       The following errors can occur, among others:
-
-       E2BIG  There is not sufficient room at *outbuf.
-
-       EILSEQ An invalid multibyte sequence  has  been  encoun-
-              tered in the input.
-
-       EINVAL An incomplete multibyte sequence has been encoun-
-              tered in the input.

-NAME
-       iconv_open  - allocate descriptor for character set con-

-
-SYNOPSIS
-       #include <iconv.h>
-
-       iconv_t iconv_open (const char* tocode, const char* fromcode);
-
-DESCRIPTION
-       The iconv_open function allocates a conversion  descrip-
-       tor  suitable for converting byte sequences from charac-
-       ter encoding fromcode to character encoding tocode.
-

-       When configured with  the  option  --enable-extra-encod-
-       ings,  it  also  provides support for a few extra encod-

-       European languages

-
-       The empty encoding name "" is equivalent to  "char":  it
-       denotes the locale dependent character encoding.
-
-       When  the  string  "//TRANSLIT"  is  appended to tocode,
-       transliteration is activated. This  means  that  when  a
-       character  cannot be represented in the target character
-       set, it can be approximated through one or several simi-
-       larly looking characters.
-
-       When  the string "//IGNORE" is appended to tocode, char-
-       acters that cannot be represented in the target  charac-
-       ter set will be silently discarded.
-
-       The  resulting  conversion  descriptor  can be used with
-       iconv any number of times. It remains valid until  deal-
-       located using iconv_close.
-
-       A  conversion  descriptor  contains  a conversion state.
-       After creation using iconv_open, the  state  is  in  the
-       initial  state.  Using  iconv  modifies the descriptor's
-       conversion  state.  (This  implies  that  a   conversion
-       descriptor  can not be used in multiple threads simulta-
-       neously.) To bring the state back to the initial  state,
-       use iconv with NULL as inbuf argument.
-
-RETURN VALUE
-       The iconv_open function returns a freshly allocated con-
-       version descriptor. In case of error, it sets errno  and
-       returns (iconv_t)(-1).
-
-ERRORS
-       The following error can occur, among others:
-
-       EINVAL The  conversion  from  fromcode  to tocode is not
-              supported by the implementation.
