virtmem: Add memory reservation system

jit: Use virtmemFindCodeMemory on both codepaths; use virtmem reservations
in order to support the JitType_SetProcessMemoryPermission codepath

virtmem: Major rewrite to support ASLR, see details:
...
- Added virtmemLock/Unlock, needed for atomic find-and-map operations
- Added virtmemFindAslr, which looks for a random free area in AslrRegion
- virtmemReserve still exists for legacy callers who rely on sequential
allocation in order to avoid race conditions from concurrent uses
- Added virtmemFindStack, which searches within StackRegion instead
- Removed virtmemReserveStack/FreeStack
- Changed shmem/thread/tmem/codememory-jit to use the new virtmem API
- Legacy jit still uses virtmemReserve

In jitTransitionToWritable() and jitTransitionToExecutable(), only run the JitType_CodeMemory handling code when it's actually needed. Actually free j->rx_addr in jitClose() for JitType_JitMemory.
