Posts: Add a $post parameter to get_the_excerpt().

Browse Source 
This allows getting the excerpt for a specific post, similar to how most other template tags work.
A deprecation notice is thrown if a boolean value is passed, which is deprecated since 2.3 and has not been used for a long time.
Adds unit tests.

Fixes #27246.
