target/aarch64: Add watchpoint support

Browse Source 
There are some breakpoint/watchpoint related code in armv8_dpm.c,
but seems not working for aarch64. Target aarch64 has its own
breakpoint implementation in aarch64.c. This commit follows the
same logic to add watchpoint support for target aarch64.

This commit also increases the size of stop_reason[] in function
gdb_signal_reply() since the old size is too small to fit in a
64-bit address, such as ffff8000115e6980.
