  [lldb][Windows] WoA HW Watchpoint support in LLDB (#108072)

This PR adds support for hardware watchpoints in LLDB for AArch64
Windows targets.

Windows does not provide an API to query the number of available
hardware watchpoints supported by underlying hardware platform.
Therefore, current implementation supports only a single hardware
watchpoint, which has been verified on Windows 11 using Microsoft
SQ2 and Snapdragon Elite X hardware.

LLDB test suite ninja check-lldb still fails watchpoint-related tests.
However, tests that do not require more than a single watchpoint
pass successfully when run individually.
