Allow valid built-in constants in function parameters

[midhunmonachan]

The fallback check for built-in constants used the parameter type alone. This made valid numeric constants such as PHP_INT_SIZE fail when passed to str_pad() because the function also has a flag parameter of type int.

The check now reports a constant only when it is listed for one of the function parameters that accepts constants. The regression test keeps the error for a misplaced STR_PAD_LEFT flag.

Closes phpstan/phpstan#15308

Checks:

• Full test suite: 22,321 tests, 98,042 assertions, 76 skipped
• bin/phpstan -v
• PHPStan coding standard
• Parallel lint on changed files

The current 2.3.x base also has pre-existing CI failures: the Turbo Extension Version Check after commit 17972fe, and PHPStan on Windows with PHP 8.1 reaching its configured 599M memory limit in shipmonk/dead-code-detector. This PR does not touch turbo-ext or that analysis path.
