dev/core#2984 - Clarify API error when component is disabled

[colemanw]

Overview

Clarifies API failures due to disabled components. Fixes https://lab.civicrm.org/dev/core/-/issues/2984

Before

Using an API from a disabled component would fail in unexpected ways with cryptic error messages.

After

Using an API from a disabled component will throw a NotImplementedException with a message like "Case API is not available because CiviCase component is disabled"

Looks good @colemanw. Test coverage makes sense.

I did some r-run using CIviCase component and CaseType API. The error message looks a lot nicer. (Old and new messages below.)

  [Symfony\Component\Debug\Exception\FatalThrowableError]                   
  Type error: array_merge(): Argument #1 must be of type array, null given  

  [Civi\API\Exception\NotImplementedException]                          
  CaseType API is not available because CiviCase component is disabled
