Add units filter on playeractions for performance (#3213)

## Description:

The ghost structure calls player actions each frame, which is costly
since it's checking for all possible actions.
This add a unit list filter in actions so if there are units it only
checks for buildability of those units.

Player actions takes 1-3% of the worker


Both performances are relevant only when a ghost structure is selected
