Introduces a function to get the min compat version.

Introduces _get_plugin_wp_min_compatible_version().

By providing a global function, for-core plugins, such as Gutenberg,
can use it to check the minimum compatible version.

It provides a more foolproof way for the plugin to handle its response.
