Also Disallow linking against non-C++ system Lua, unless configuring with -Dworkaround_noncpp_lua=true, add -Dworkaround_elusive_bzip2 and friends, and get rid of the -image_base hack for macos.
All of these are options that are specific to our ghactions builds and not something we want downstream and package maintainers to be locked into using.
This is how we'll handle systems where the cert bundle and cert directory is stored where mbedtls doesn't expect it.
Also update tpt-libs to get new curl and mbedtls.
Command line is limited in length on windows so meson/ninja puts it in a response file and passes that to the linker instead. Only problem is, ninja -v displays only the part of the command line where it tells link.exe where the response file is, not what's in the response file. So I just had the script print it. Care must also be taken for the script to properly fail if ninja fails, but not before the command line is printed.
Also add /GL and /LCTG to msvc command lines because they can't hurt. Right?
Also Factor out app constants that mods might change into Meson options and clean up format::URLEncode in the process, convert app and document icon data in arrays to actual images, actualize AppStream data for possible future packaging, add alternative command line format for opening filesystem saves and ptsave URLs, fix a memory leak in Platform::GetCwd, and add format::URLDecode.
Also restructure meson.build and the ghactions workflow a bit, and enable -ffunction-sections and -fdata-sections.
Note that starcatcher uploads have not been tested and most likely don't work.
Also fix the first mouse click not being detected on windows with sdl 2.0.20. Apparenlty, we need SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH set to 1 for it to be detected.
Certain file managers need this figure out that the executable is actually executable. The problem is further complicated by meson being uncooperative and not implementing its own -Db_pie=false correctly.
