+* LLDB now supports hardware watchpoints for AArch64 Windows targets. Windows
+  does not provide API to query the number of supported hardware watchpoints.
+  Therefore current implementation allows only 1 watchpoint, as tested with
+  Windows 11 on the Microsoft SQ2 and Snapdragon Elite X platforms.

I have run all tests individually and only those test fail now which require more than single hardware watchpoint resources. I am not really sure why ninja check-lldb fails the watchpoint test even when run single threaded but all tests pass when they are run via dotest.py individually.
