png: Split library to thirdparty dir and allow unbundling Uses the new structure agreed upon in #6157, but the thirdparty/ folder does not behave following a logic similar to that of modules/ yet. The png driver can't be moved to a module as discussed in #6157, as it's required by core together with a few other ImageLoader implementations (see drivers/register_driver_types.cpp:register_core_driver_types()) Dropped the possibility to disable PNG support, it's a core component of Godot.

if (env["libpng"] == "builtin"):
thirdparty_dir = "#thirdparty/libpng/"
modules: Clone env in each module This allows to pass include paths and flags only to a given thirdparty library, thus preventing conflicts between their files (e.g. between opus and openssl which both provide modes.h. This also has the nice effect of making the compilation command smaller for each module as it no longer related to all other modules, only the final linking brings them together. This however requires adding manually the ogg include path in opus and vorbis when building against the builtin ogg, since it is no longer in the global env. Also simplified template 'thirdparty_<module>_sources' to 'thirdparty_sources'. "Core" modules like cscript, gdscript, gridmap, ik and virtual_script still use the main env_modules, but it could be changed if need be.
