Add cmake flag to control aot intrinsics (#3261)

Browse Source 
Add cmake variable `-DWAMR_BUILD_AOT_INTRINSICS=1/0` to enable/disable
the aot intrinsic functions, which are normally used by AOT XIP feature, and
can be disabled to reduce the aot runtime binary size.

And refactor the code in aot_intrinsics.h/.c.
