#42513: WP_Theme::get_post_templates() is extremely inefficient for large themes

-----------------------------------------+-----------------------------
WP_Theme::get_post_templates() uses file_get_contents() to read the
complete contents of each theme php file in the root of a theme into
memory, twice, and processes the result with a custom Regular Expression.
As a result, significantly more data than necessary is processed when
loading large themes.
In addition, because the standard get_file_data() function is not called
(as it is with all other header comments), the "extra_{$context}_headers"
filter is never called, which is inconsistent behavior with other
file_header related operations, such as the WP_Theme constructor.
