Query: Check if $wp_query is set in is_main_query().

Browse Source 
This avoids a PHP fatal error and triggers a `_doing_it_wrong()` notice if `is_main_query()` is called too early, bringing consistency with all the other `is_*()` conditionals: `is_single()`, `is_home()`, etc.

Follow-up to [16947], [17068], [17083], [18699], [37985].
