Correct some types in `wp-admin/*`-location files' doc blocks.

See #30224.

Add some unit tests for `is_object_in_term()`.

These tests check a number of the ways that different kinds of values for
`$terms` (integers that match term_id, strings that match term_id or name or
slug) are handled.

See #29467.

git-svn-id: https://develop.svn.wordpress.org/trunk@30204 602fd350-edb4-49c9-b593-d223f7449a82
In `in_object_in_term()`, only check numeric string values against term_id.

The previous `in_array()` check was playing too loose with mixed types, such
that a string like '10_term_name' would incorrectly match a term_id 10.

Introduce `term_template` param to `get_the_taxonomies()`.

This parameter allows theme and plugin authors to specify the formatting they
would like on the term links as they are parsed into the taxonomy list.

git-svn-id: https://develop.svn.wordpress.org/trunk@30209 602fd350-edb4-49c9-b593-d223f7449a82
Improve docblocks for `get_the_taxonomies()` and `the_taxonomies()`.

* In `the_taxonomies()`, only document those arguments that are specific to the function. Arguments shared with `get_the_taxonomies()` should be documented in the later function's docblock.
* Add $args hash documentation to `get_the_taxonomies()`.
* Remove the redundant default argument definition in `the_taxonomies()`.

Fixes #27238.
