Bootstrap: Make `wp_is_ini_value_changeable()` compatible with PHP 5.2.6 - 5.2.17.

There is a bug in PHP 5.2.6 - 5.2.17 (https://bugs.php.net/bug.php?id=44936, https://3v4l.org/IL0A2) which changes the access level of a setting to 63 after `ini_set()` was called.
To continue comparing the access value against `INI_ALL` and `INI_USER` use the bit operator `& 7`:

* `1 & 7 === 1` (INI_USER)
* `2 & 7 === 2` (INI_PERDIR)
* `4 & 7 === 4` (INI_SYSTEM)
* `7 & 7 === 7` (INI_ALL)
* `63 & 7 === 7` (INI_ALL)

See [38015].
See #32075.
