Move code-gen aux symbols from ghc-internal to rts
These symbols were all previously defined in ghc-internal and made the
dependency structure awkward, where the rts may refer to some of these
symbols and had to work around that circular dependency the way
described in #26166.
Moreover, the code generator will produce code that uses these symbols!
Therefore, they should be available in the rts:
PRINCIPLE: If the code generator may produce code which uses this
symbol, then it should be defined in the rts rather than, say,
ghc-internal.
That said, the main motivation is towards fixing #26166.
Towards #26166. Pre-requisite of !14892

rts: Avoid static symbol references to ghc-internal
This resolves #26166, a bug due to new constraints placed by Apple's
linker on undefined references.
One source of such references in the RTS is the many symbols referenced
in ghc-internal. To mitigate #26166, we make these references dynamic,
as described in Note [RTS/ghc-internal interface].
Fixes #26166

compiler: Rename isMathFun -> isLibcFun
This set includes more than just math functions.

compiler: Add libc allocator functions to libc_funs
Prototypes for these are now visible from `Prim.h`, resulting in
multiple-declaration warnings in the unregisterised job.

rts: Minimize header dependencies of Prim.h
Otherwise we will end up with redundant and incompatible declarations
resulting in warnings during the unregisterised build.
