[php-src] PR #22927: Convert usage of `php_error`/`zend_error` to `php_error_docref`

Pull Request: https://github.com/php/php-src/pull/22927 Author: NattyNarwhal Not yet complete. Some notes so far: * The goal is to eventually eliminate php_error as an alias for zend_error, make error reporting more consistent, and eventually figure out some symmetry between php_verror and php_error_docref naming wise. zend_error should remain, but there may be quite a bit of overlap anyways. * I'm starting with ext since this usually is for functions where the php_error_docref output makes sense when prefixing with a function name and optionally arguments (or indicating phase of startup/shutdown). There are some notable exceptions (some stuff related to arrays and comparisons) that do not work in that context. * There may be some stuff in Zend and sapi too. * Deprecation messages tend to repeat the function name, so I haven't changed those. Perhaps there should be some kind of function for consistent deprecation messages? * The changes to ext/soap are a bit wider, getting rid of some pointless macros and replacing the SOAP-ERROR prefix with the function prefix from docref output. This could be broken out into a separate PR. * A lot are in hard to reach areas without tests to validate. Some of these may make more sense as exceptions, for instance.
