REST API: allow overriding excerpt length.

Browse Source 
This can be used by the excerpt block in the editor to change the excerpt length without filtering `excerpt_length` in a conflicting way. This enhancement still needs a corresponding change on the Gutenberg side.

Props swissspidy, antonvlasenko, mukesh27, azaozz, andraganescu, timothyblynjacobs.
Fixes #59043.
