Multisite: Ensure that switching sites resets the current theme directory globals.

The globals introduced in [56635] to cache the current theme directories in memory were not considering switching sites in a multisite network. This changeset addresses the bug including test coverage.

Props codex-m, jeremyfelt, costdev, joemcgill.
Merges [56974] to the 6.4 branch.
Fixes #59677.
