[Windows] Added support of watchpoints to `NativeProcessWindows`
Summary: This patch adds support of watchpoints to the new `NativeProcessWindows` plugin. The same tests as in D67168 pass with these changes when the old plugin is turned off, so they will cover this functionality when the old plugin is gone.
