Hello!

Currently, watchpoints don't work on Windows (this can be reproduced with the 
existing tests). This patch fixes the related issues so that the tests and 
watchpoints start working.

Here is the list of tests that are fixed by this patch (on Windows, checked in 
**release/18.x** branch):
- commands/watchpoints/hello_watchpoint/TestMyFirstWatchpoint.py
- commands/watchpoints/multiple_hits/TestMultipleHits.py
- commands/watchpoints/multiple_threads/TestWatchpointMultipleThreads.py
- commands/watchpoints/step_over_watchpoint/TestStepOverWatchpoint.py
- commands/watchpoints/unaligned-watchpoint/TestUnalignedWatchpoint.py
- commands/watchpoints/watchpoint_commands/TestWatchpointCommands.py
