Joe McGill 618e42240f Themes: Use original template paths when switching blogs.
This fixes a bug introduced by [57129] and [56635] in which deprecating the previous  `TEMPLATEPATH` and `STYLESHEETPATH` constants in favor of `get_template_directory()` and `get_stylesheet_directory()` functions caused the active theme template path to change when using `switch_to_blog()`.

This introduces a new function, `wp_set_template_globals()`, which is called during the bootstrap process to store the template paths to new globals values `$wp_template_path` and `$wp_stylesheet_path`. This restores behavior to how things worked prior to [56635] but retains the ability for template values to be reset for better testability.

Related #18298, #60025.

Props joemcgill, flixos90, mukesh27, swissspidy, manfcarlo, metropolis_john, jeremyfelt.
Fixes #60290.
