py/misc: Add a way to detect sanitizer builds.

Browse Source 
Clang and gcc>=14 can use __has_feature() to detect if a sanitizer
is enabled, but older GCC has no mechanism - need to set a macro
explicitly for this to be recognised.

Necessary for increasing some resource limits in sanitizer builds.
Important not to use to avoid real issues!
