Add an ArgumentParser helper for integers

Description

Add an ArgumentParser helper for integers

Summary:
Ref T13676. With increased PHP8.1 strictness around null, it seems reasonable to add some convenience parsing to "PhutilArgumentParser".

Add a helper function for parsing integers.

Test Plan:
See next change. Tried these arguments:

--count ''
--count asdf
--count 0
--count -3
--count 999999999999999999999999999999999999999999999234
--count 5

Got sensible parsing and appropriate feedback in all cases.
