exec.c: Rename cpu_physical_memory_write_rom_internal()

Rename cpu_physical_memory_write_rom_internal() to
address_space_write_rom_internal(), and make it take
MemTxAttrs and return a MemTxResult. This brings its
API into line with address_space_write().

This is an internal function to exec.c; fixing its API
will allow us to change the global function
cpu_physical_memory_write_rom().
