  tsan: remove indirection when selecting the active mapping

Currently there are 2 levels when selecting the active mapping:
the branchy ifdef tree + another ifdef tree in SelectMapping.
Moreover, there is an additional indirection for some platforms
via HAS_48_BIT_ADDRESS_SPACE define. This makes already complex
logic even more complex and almost impossible to read.
Remove one level of indirection and define the active mapping
in SelectMapping.

Depends on D107742.
