REST API: Introduce _pretty query parameter to opt in to JSON_PRETTY_PRINT. 

Add support for a "_pretty" meta-parameter on all REST controllers which instructs WordPress to return pretty-printed JSON, for better readability when inspecting endpoint responses in curl output or certain developer tools.

Introduce the "rest_json_encode_options" filter to permit site owners to control this behavior globally.

Fixes #41998.
