Move all code from src/setup.py, src/fpickle_setup.py to sage_setup

[mkoeppe]

This is preparation for splitting sagelib into separate distutils packages, but a useful cleanup in any case.

As a follow-up of this ticket, as part of Meta-ticket #29705, the remaining very short src/setup.py should probably be moved to build/pkgs/sagelib/src/ (alongside a symlink src -> SAGE_ROOT/src)

Depends on #29411
