sdl2.m4: Deprecate AM_PATH_SDL2 in favour of PKG_CHECK_MODULES 

AM_PATH_SDL2 doesn't add much beyond PKG_CHECK_MODULES, and having a
special m4 macro for every library that you might depend on scales
poorly.

The macro does add special support for macOS frameworks, but that feature
was broken for around 6 years without anyone noticing (#6141), and is
likely to be only rarely useful according to comments on #6141.

Resolves: #6140
