cpu: move debug_check_watchpoint to tcg_ops

Browse source 
commit 568496c0c0 ("cpu: Add callback to check architectural") and
commit 3826121d92 ("target-arm: Implement checking of fired")
introduced an ARM-specific hack for cpu_check_watchpoint.

Make debug_check_watchpoint optional, and move it to tcg_ops.
