REST API: Fix changing parameters with `set_param()` for some requests. 

Prior to this commit, `WP_Rest_Request::get_param()` traversed through the parameter order but `WP_Rest_Request::set_param()` did not. For JSON requests (and likely other situations as well), this meant that changing a parameter with `set_param()` would have no effect on `get_param()`.

Props TimothyBlynJacobs.
Fixes #40344.
