target-xtensa: add DBREAK data breakpoints
Add DBREAKA/DBREAKC SRs and implement DBREAK breakpoints as debug
watchpoints.
This implementation is not fully compliant to ISA: when a breakpoint is
set to an unmapped/inaccessible memory address it generates TLB/memory
protection exception instead of debug exception.
See ISA, 4.7.7.3, 4.7.7.6 for more details.
