Boone Gorges 499d1b74ba Don't cache `WP_Term` objects in `wp_get_object_cache()`.
The data stored in the cache should be raw database query results, not
`WP_Term` objects (which may be modified by plugins, and may contain additional
properties that shouldn't be cached).

If term relationships caches were handled in `wp_get_object_terms()` - where
a database query takes place - it would be straightforward to cache raw data.
See #34239. Since, in fact, `get_the_terms()` caches the value it gets from
`wp_get_object_terms()`, we need a technique that allows us to get raw data
from a `WP_Term` object. Mirroring `WP_User`, we introduce a `data` property
on term objects, which `get_the_terms()` uses to fetch cacheable term info.

Fixes #34262.

Boone Gorges 5b32e27a00 Fix 'exclude_tree' in `wp_list_categories()`.
The 'exclude_tree' parameter must be compatible with 'hierarchical';
previously, 'hierarchical' canceled it out. This changeset also makes it so
that 'exclude_tree' is compatible with 'exclude'. When both are passed, and
'hierarchical' is true, the descendant trees of terms in both parameters will
be excluded from matched terms.

Boone Gorges c243d7070e Introduce `'the_category_list'` filter.
Used to filter categories as structured data, before building markup in
`get_the_category_list()`.

We use this filter in addition to upstream filters (such as
'get_the_categories'`) because those upstream filters are used in numerous
contexts, while `'the_category_list'` is always used for generating markup
for display.

Boone Gorges ccb9c641f4 Introduce `hide_title_if_no_cats` parameter to `wp_list_categories()`.
When generating a `<ul>` using `wp_list_categories()`, a title `<li>` element
is put at the top of the term list. Current behavior is that this title `<li>`
appears even when no terms are found. The new `hide_title_if_no_cats` param
allows developers to specify that the title should be hidden when the term list
is empty.

Boone Gorges 8b15f8be3d In `Walker_CategoryDropdown::start_el()`, cast values to strings before deciding whether to append 'selected' attribute.
As of [32484], `wp_dropdown_categories()` uses the `$value_field` value to
decide whether a given `<option>` should be 'selected'. However, `$value_field`
can refer to a value that is a string, such as a category's slug. This causes
problems when doing a loose comparison (`==`) with the value of the `'selected'`
parameter, which defaults to `0`, because when doing a loose comparison
between an integer and a string, PHP will cast the string to an integer. This
creates false matches, resulting in `<option>` elements getting a 'selected'
attribute incorrectly.

We address the issue by casting the comparison values to strings, and then
using the strict comparison operator `===`.

Scott Taylor fe6b5983df In PHP 5.0.0, `is_a()` became deprecated in favour of the `instanceof` operator. Calling `is_a()` would result in an `E_STRICT` warning.
In PHP 5.3.0, `is_a()` is no longer deprecated, and will therefore no longer throw `E_STRICT` warnings.

To avoid warnings in PHP < 5.3.0, convert all `is_a()` calls to `$var instanceof WP_Class` calls.

`instanceof` does not throw any error if the variable being tested is not an object, it simply returns `false`.
