Fix font lock regex for user defined constant in PHP

The old regex also captured functions with two or more
uppercase characters.  This new regex fixes that issue.
* lisp/progmodes/php-ts-mode.el (php-ts-mode--font-lock-settings):
New regex that match only user-defined constants.  (Bug#71593)

(cherry picked from commit a4fe4ca93cfdc835ecd8c5dcc98c201a1eefb546)
