Clarify the code in `nla_draw_strip()` by extracting some flags into booleans, and renaming some variables. - `solo` is flipped in value, and renamed to `is_other_track_soloed`, as this is what is actually modelled by the variable. - The check for the `NLASTRIP_FLAG_INVALID_LOCATION` flag is stored in a `const bool` to aid in debugging. No functional changes. Pull Request: https://projects.blender.org/blender/blender/pulls/120828
