target/mips: Make CPU/FPU regnames[] arrays global

The CPU/FPU regnames[] arrays is used in mips_tcg_init() and
mips_cpu_dump_state(), which while being in translate.c is
not specific to TCG.

To be able to move mips_cpu_dump_state() to cpu.c, which is
compiled for all accelerator, we need to make the regnames[]
arrays global to target/mips/ by declaring them in "internal.h".
