Fix #53854: Missing constants for compression type

The constants have already been added long ago. This patch just adds a PHPT
which checks the recognition of the respective compression methods.
Unfortunately, I've not been able to assemble a zip with all compression
methods.

+--TEST--
+Recognition of compression methods
+--DESCRIPTION--
+This test is supposed to cover all compression methods that are recognized by
+libzip, but for now only 6 methods are available in compression_methods.zip.
+The zip and the test should be extended, if possible.
+--SKIPIF--
+<?php
+if (!extension_loaded('zip')) die('skip zip extension not available');
+?>
+--FILE--
+<?php
+$methods = array(
+    'store'     => ZipArchive::CM_STORE,
+    'deflate'   => ZipArchive::CM_DEFLATE,

+    'bzip2'     => ZipArchive::CM_BZIP2,
+    'lzma'      => ZipArchive::CM_LZMA,
