Final

Used makeprojects to generate all the projects. Verified that all the samples work perfectly on all supported compilers and platforms. Simplfied the Watcom library naming by renaming it to QTWatcom.lib to make it obvious that it's for Watcom. Update some Quicktime headers for __cdecl for callbacks (Can cause issues if VS 2022 is set to "fastcall"), fixed.

Unless there are bugs found, this is the "stick a fork in it" version.
