Themes: Deprecate usage of `TEMPLATEPATH` and `STYLESHEETPATH` constants. While generally the functions `get_template_directory()` and `get_stylesheet_directory()` were long recommended to use to get the parent or child theme directory, the `TEMPLATEPATH` and `STYLESHEETPATH` constants were still used in a few places in core, most importantly in template related logic. The remaining usage was problematic as it prevented testability of certain key components of WordPress core. This changeset replaces all remaining usage with the corresponding functions and effectively marks these constants as deprecated. It also adds test coverage accordingly and even unlocks some existing, previously commented out test coverage to work as expected. Performance of the new approach has been benchmarked and shows no notable differences. Yet, given that the current theme directories are not expected to change within a regular WordPress page load, the `get_template_directory()` and `get_stylesheet_directory()` functions were amended with in-memory caching of the result, unless one of the defining values is being filtered.
