Automated vcpkg, Win7+32bit support

• Prebuilts package is now generated from scratch using Github CI
• As a result, all libraries were updated to latest version available on vcpkg
• Now only boost components that are required for vcmi are included into the package (due to issues with boost-python on Win7/32 bit)
• Package now archived as .txz instead of .7z (hopefully will improve extraction times)
• Added / restored support for 32-bit builts
• VCPKG now targets Windows 7

TBB fix

TBB no longer knows what debug is to avoid cpack putting debug libs to installation package

v1.6

• Added qt5-translations
• Added enet

v1.5

Update vcpkg to reflect vcmi 1.0 latest changes

Add Fuzzylite

Added prepackaged fuzzylite to avoid duplicating symbols issue on CI

Add Intel TBB

Added Intel TBB for Nullkiller AI

Windows Deps v1.2

Same as v1.1, but with hotpatched Qt base files to version 5.12.1-2.

Since version 1.1 seems to contain whole qt, and this package contains only core qt files, there are some qt 5.8 leftovers which should not disrupt anything as they are not really needed currently.

Windows Deps v1.1

Same as v1, but with luajit 2.0.5-1 added.
