target/mips: Add simple user-mode mips_cpu_do_interrupt()
The #ifdef'ry hides that the user-mode implementation of
mips_cpu_do_interrupt() simply sets exception_index = EXCP_NONE.
Add this simple implementation to tcg/user/tlb_helper.c, and
the corresponding Meson machinery to build this file when user
emulation is configured.
