Fix osx-arm64 compilation

This reverts commit 4ec1888c.

Add PS2 compilation

DJGPP, NGC and Wii compilation

Add WiiU compilation

Add dingux compilation directives

Simplify building of simavr and make arduous compileable on buildbot libretro platforms

Platforms I tested:
* Android x64 and arm64. 60fps/fullspeed
* Linux i686 and x64. 60fps/fullspeed
* Windows i686 and x64. 60fps/fullspeed
* Emscripten. 60fps/fullspeed
* Libnx (Switch) 55fps/92% on stock performance or
                 60fps/full speed on boost performance
* 3DS. 30fps/about 50% speed
* PSP. 13.5fps/about 22.5% speed

Not tested beyond compilation but should work:
* Android i686 and arm32
* OSX i686/x64/aarch64
* Vita

Skipped as cmake templates aren't agreed yet:
* iOS/tvOS
* PS2
* Dingux

Skipped big-endian platforms as I don't have one to test now:
* osx-ppc
* wiiu
* wii
* ngc
* psl1ght

Windows has no strsep. Check for strsep presence and if none is found use own
copy of glibc strsep

%x is specifically for unsigned int but uint32_t may be unsigned int or
unsigned long. If it's unsigned long it's de-facto the same as unsigned int
but without a cast compilation fails.

This pins the standard to c99 and so allows c99 features even if compiler
defaults to lower standard

uint fails for several buildbot targets and since it's used in a single
place only, just replace it with unsigned int

simavr.cmake and simavr patches are not used anymore

Pulling the tree in build phase is nice but other cores use submodules and they
are easier to deal with.

Running subcompilation using makefile for simavr is very difficult for the cases
of cross-compile like is needed for all the consoles. Hence let's just pull
required files directly into the project. With few tricks they don't even need
any changes simplifying the entire handling

Many platforms use a suffix _${platform}.${extension} as suffix. Add it
when necesarry.

Various libretro-centric improvements

Without hex file the emulator crashes on any RAM access. Moreover
without game the emulator currently has no meaningful behaviour.
So disable no-game mode

Without it save/restore/rewind almost work but result in a shifted
or garbled screen as page/columns and sometimes other registers do not
match anymore
