Remove ANGLE

This marks the end of EGL and OpenGL ES support on Windows.

The concepts of -opengl dynamic, -opengl desktop, QT_OPENGL=software,
etc. remain unchanged, with the exception of the disapperance of
everything ANGLE related.

CMake builds now work identically to qmake on Windows: they default to
'dynamic' OpenGL on Windows, unless -DINPUT_opengl=desktop is specified.

On Windows, Qt 6 is expected to default to the "dynamic" OpenGL model by
default, just like Qt 5.15. This can be changed by switching to "desktop"
OpenGL, which will link to opengl32 (publicly, so other libs and applications
will do so as well) and disallows using another OpenGL DLL.

The "dynamic" mode is essential still because the fallback to a software
rasterizer, such as the opengl32sw.dll we ship with the Qt packages,
has to to work exactly like in Qt 5, the removal of ANGLE does not
change this concept in any way (except of course that the middle option
of using ANGLE is now gone)

When it comes to the windows plugin's OpenGL blacklist feature, it works
like before and accepts the ANGLE/D3D related keywords. They will
then be ignored. Similarly, requesting QT_OPENGL=angle is ignored (but
will show a warning).

The D3D11 and DXGI configure time tests are removed: Qt 5.14 already
depends on D3D 11.1 and DXGI 1.3 headers being available unconditionally
on Win32 (in QRhi's D3D11 backend). No need to test for these.

[ChangeLog][Windows] ANGLE is no longer included with Qt. Dynamic OpenGL
builds work like before but ANGLE is no longer an option. OpenGL proper
or an alternative opengl32 implementation are the two remaining options
now. Attempting to set QT_OPENGL=angle or Qt::AA_UseOpenGLES will have
no effect on Windows.

- * Adopters may modify this file to suit their platform. Adopters are
- * encouraged to submit platform specific modifications to the Khronos
- * group so that they can be included in future versions of this file.
- * Please submit changes by sending them to the public Khronos Bugzilla
- * (http://khronos.org/bugzilla) by filing a bug against product
- * "Khronos (general)" component "Registry".
- *
- * A predefined template which fills in some of the bug fields can be
- * reached using http://tinyurl.com/khrplatform-h-bugreport, but you
- * must create a Bugzilla login first.
- *
- *
- * See the Implementer's Guidelines for information about where this file
- * should be located on your system and for more details of its use:
- *    http://www.khronos.org/registry/implementers_guide.pdf
- *
- * This file should be included as
- *        #include <KHR/khrplatform.h>
- * by Khronos client API header files that use its types and defines.
- *
- * The types in khrplatform.h should only be used to define API-specific types.
- *
- * Types defined in khrplatform.h:
- *    khronos_int8_t              signed   8  bit
- *    khronos_uint8_t             unsigned 8  bit
- *    khronos_int16_t             signed   16 bit
- *    khronos_uint16_t            unsigned 16 bit
- *    khronos_int32_t             signed   32 bit
- *    khronos_uint32_t            unsigned 32 bit
- *    khronos_int64_t             signed   64 bit
- *    khronos_uint64_t            unsigned 64 bit
- *    khronos_intptr_t            signed   same number of bits as a pointer
- *    khronos_uintptr_t           unsigned same number of bits as a pointer
- *    khronos_ssize_t             signed   size
- *    khronos_usize_t             unsigned size
- *    khronos_float_t             signed   32 bit floating point
- *    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
- *    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
- *                                         nanoseconds
- *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
- *    khronos_boolean_enum_t      enumerated boolean type. This should
- *      only be used as a base type when a client API's boolean type is
- *      an enum. Client APIs which use an integer or other type for
- *      booleans cannot use this as the base type for their boolean.
- *
- * Tokens defined in khrplatform.h:
- *
- *    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
- *
- *    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
- *    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
- *
- * Calling convention macros defined in this file:
- *    KHRONOS_APICALL
- *    KHRONOS_APIENTRY
- *    KHRONOS_APIATTRIBUTES
- *
- * These may be used in function prototypes as:
- *
- *      KHRONOS_APICALL void KHRONOS_APIENTRY funcname(
- *                                  int arg1,
