REST API: Tweak permission checks for taxonomy and term endpoints

Browse Source 
To match behaviour in the Classic Editor, we need to slightly loosen permissions on taxonomy and term endpoints. This allows users to create terms to assign to a post that they're editing.

Merges [43440] to the 4.9 branch.

Props danielbachhuber.
Fixes #44096.
