Add/qm compat

[trepmal]

• Adds curly braces throughout. Helps when doing manual debugging
• Adds do_action calls to work with Add QM Panel to display info about js/css concatenation vip-go-mu-plugins#5693. Will do nothing without that QM plugin. Does not log comprehensively, but covers common issues for excluding scripts such as being explicitly filtered or external urls. Lists contents of grouped assets.

Helper plugin, just enqueues a bunch of CSS and JS files:
enqueue-scripts.zip

Thanks @trepmal! Do you mind refactoring the max files - it's now hardcoded in 3 places and might be good to abstract out at this point.

Also "TOO LARGE" doesn't tell me much. As a user, I'm not sure what that means. Something like "Skipping bundling because it contains too many items (x out of LIMIT).
