Jb Audras a925aabc9c Themes: Add a hook to filter theme header image URL.
This changeset introduces the `get_header_image` filter, which can be used to modify header image URL returned by `get_header_image()`, in themes that support the Header Image feature. 

Props hztyfoon, audrasjb, mukesh27, SergeyBiryukov, costdev.
Fixes #56180.
