This implements functionality to handle DataBreakpointInfo request and
SetDataBreakpoints request.
Previous commit
8c56e78ec5
was reverted because setting 1 byte watchpoint failed in the new test on
ARM64. So, I changed the test to setting 4 byte watchpoint instead, and
hope this won't break it again. It also adds the fixes from
https://github.com/llvm/llvm-project/pull/81680.
