Simplify console output helpers to macros over php_error_docref

Replace the APC_PRINT_FUNCTION macro that generated four exported
apc_error/apc_warning/apc_notice/apc_debug functions with thin variadic
macros in apc.h that forward directly to php_error_docref(), and drop the
generator block from apc.c entirely.

This also fixes the build against PHP 8.6-dev: php/php-src@0a12b3e8268
removed the params argument from php_verror(), which the old
APC_PRINT_FUNCTION body called. Forwarding to php_error_docref() instead
sidesteps php_verror() altogether and works on all supported versions.
