Properly indicate wrapping of wx.CallAfter while monkeypatching

[XLTechie]

Link to issue number:

None

Summary of the issue:

The monkeypatch for wx.CallAfter didn't indicate wrapping.

>>> import wx
>>> help(wx.CallAfter)
Help on function wx_CallAfter_wrapper in module monkeyPatches.wxMonkeyPatches:

wx_CallAfter_wrapper(func, *args, **kwargs)

Description of user facing changes

None

Description of development approach

Imported wraps from functools, and added @wraps to the wrapper.
From a build after the modification:

>>> import wx
>>> help(wx.CallAfter)
Help on function CallAfter in module wx.core:

CallAfter(callableObj, *args, **kw)
    Call the specified function after the current and pending event
    handlers have been completed.  This is also good for making GUI
    method calls from non-GUI threads.  Any extra positional or
    keyword args are passed on to the callable when it is called.

Also converted the apply() function's comment into a docstring.

Testing strategy:

Ran with the fix in a portable copy of NVDA.
I found no difficulties.

Known issues with pull request:

I do not know what original STR prompted the wrapping of this callable. As far as I can tell, it was originally introduced in 528d570, but there is no commit message for this change.

Did some issue/pr searches, but couldn't find any reasoning there either. So I don't know what caused the wrapping, to test that specifically. Do you remember, @michaelDCurran?
