Add support for handling archive files with libarchive

libarchive is a multi-format archive and compression library
written in C and licensed under the new BSD license. Usage of
libarchive brings in support for additional archive formats
(in addition to 7z) with the installer framework, like zip and
tar, with several available compression methods like gzip, bzip2
and xz.

libarchive will coexist as a supported archive format handler
with the LZMA SDK currently used in the framework, which will
continue to be used for handling the 7-Zip file format.

This change introduces classes for handling archive operations
using both libraries, removes most calls to the old Lib7z facade
and migrates the code base to use the new handling methods.
