accel/tcg: create a thread-kick function for TCG

Round-robin TCG is calling into cpu_exit() directly.  In preparation
for making cpu_exit() usable from all accelerators, define a generic
thread-kick function for TCG which is used directly in the multi-threaded
case, and through CPU_FOREACH in the round-robin case.

Use it also for user-mode emulation, and take the occasion to move
the implementation to accel/tcg/user-exec.c.
