[sanitizer] Add definitions for Myriad RTEMS platform 

Introduce two definitions to be used by the Myriad RTEMS port of the
ASan run-time: SANITIZER_MYRIAD2 for the platform and SANITIZER_RTEMS
for the OS.  We expect to use SANITIZER_MYRIAD2 to guard the portion
of the port corresponding to Myriad's unique memory map, and
SANITIZER_RTEMS for most of the rest.

// By default we allow to use SizeClassAllocator64 on 64-bit platform.
// But in some cases (e.g. AArch64's 39-bit address space) SizeClassAllocator64
// does not work well and we need to fallback to SizeClassAllocator32.
