accel/tcg: Move most of gen-icount.h into translator.c

The only usage of gen_tb_start and gen_tb_end are here.
Move the static icount_start_insn variable into a local
within translator_loop.  Simplify the two subroutines
by passing in the existing local cflags variable.

Leave only the declaration of gen_io_start in gen-icount.h.
