gdb: delay python initialisation until gdbpy_finish_initialization

Delay Python initialisation until gdbpy_finish_initialization.

This is mostly about splitting the existing gdbpy_initialize_*
functions in two, all the calls to register_objfile_data_with_cleanup,
gdbarch_data_register_post_init, etc are moved into new _initialize_*
functions, but everything else is left in the gdbpy_initialize_*
functions.

Then the call to do_start_initialization (in python/python.c) is moved
from the _initialize_python function into gdbpy_finish_initialization.

There should be no user visible changes after this commit.
