Query: Discard non-scalar 'm' instead of attempting to sanitize.

`WP_Query` discards most non-array date values ('year', 'monthnum', etc) by
casting to integer. Since [25138], the 'm' parameter has been handled
as a string; see #24884. However, the string-handling introduced in [25138]
blindly attempted to handle arrays and other non-scalar types as strings,
resulting in PHP notices and invalid MySQL syntax.

Props vortfu.
Fixes #36718.
