Flyinghead 32e3e7d9c5 vmem: no more 4GB vmem mode. only map elan RAM in naomi2 mode
Do not attempt to reserve 4GM of virtual space on 64-bit hosts. Use
512MB everywhere.
Don't map elan RAM if not needed and dont protect/unprotect it in
memwatch.

Flyinghead e3d95f2258 wince: unify _vmem and vmem32. Use 4GB virtual space on 64-bit arch
On 64-bit architectures, _vmem first tries to allocate 4GB then falls
back to 512 MB.
The same virtual space is now used by _vmem and vmem32 (mmu)

David Guillen Fandos aa4fc8dd60 Move cache invalidation to vmem_platform and implement NO_RWX on arm64
Still not functional yet, this commit breaks arm64 on android for instance.
Rewrites are not yet figured out, will push them in the next commit.

David Guillen Fandos 3b760f9869 Add FEAT_NO_RWX_PAGES and implement it for x64 CPU (Win and Linux)
Tested: Both with and without the feature, works only for x64 CPUs for
now, but supported in both windows and linux (see vmem implementation
for it, using mem-mapped files).

David Guillen Fandos 1a2b1c8672 Remove traces of memory manager from Jit driver.
Still stuff to be removed in the Naomi file handler and the ARM
AREC, which need to get ported to the new vmem interface.

David Guillen Fandos b74db6ef53 Moving vmem to separate files with a proper interface.
Works so far for Linux and Android, need to do some testing on Windows.

Stefanos Kornilios Mitsis Poiitidis 67ecd6d9f9 vmem: Automatic fallback to slowpath if alloc fails
This consolidates some of the work done for TARGET_NO_NVMEM and
feat/no-direct-memmap. If nvmem is disabled at compile time or alloc
fails _nvmem_enabled() will return false. Various other fixes
and cleanups all around.
