Fix some mouse gestures (#18906)
Follow-up to #18883
Fixes #18913
### Summary of the issue:
Some gestures that control the mouse are broken. These include
left/right mouse button lock/unlock, and navigator object default
action.
### Description of user facing changes:
They work again.
### Description of developer facing changes:
None.
### Description of development approach:
Updated `mouseHandler.executeMouseEvent` to send `0` instead of `None`
as the value of `dwExtraInfo`. This is necessary as `dwExtraInfo` is
correctly declared as `ULONG_PTR` since #18883, so ctypes will not
accept `None`.
### Testing strategy:
Ran from source and tested clicking and locking/unlocking the left and
right mouse buttons, as well as activating the navigator object.
### Known issues with pull request:
None
