Cleanable cleanup (#52477)

* Don't initialize the atom_colours list on atoms until it's actually needed

* Moved bloody_hands var to mob/living/carbon/human instead

* Added COMSIG_COMPONENT_CLEAN_RADIATION signal to reduce moms spaghetti

The shower and suit storage unit now calls this signal instead of either doing it manually or doing it via the washed proc

* Cleaned up carbon washing, renamed washed to wash

* The wash proc now doesn't take the washer as first arg because that wasn't used anywhere
* The wash strength is no longer optional
* Carbons now overrides the wash proc instead of using the signal
* Properly check for obscuredness before washing any equipped items
* Properly wash all items and bloody hands etc
* Added clean_lips proc for humans for cleaning any lipstick

* Cleaned up washing. Washy stuff now calls wash instead of calling the clean signal directly

* Renamed is_cleanable to ismopable, gives this category a more fitting purpose. Many things beyond floor decals are cleanable. It is now also determined using the atom layer instead to make it more generic.
* Properly utilize the is_cleanable define
* Added wash override for turfs where they also wash any mopables on the same tile
* Space cleaner and cleaning element etc now simply washes the mob instead of doing its own manual cleaning on ~some~ equipped items

* Non-component washables now simply override wash instead of registering for the clean signal

* Fixed some left over clean signal registers not returning true

* Added clean_strength var to space cleaner

* Moved human wash proc next to the other washing procs

* Also wash glasses and mask if not obscured when washing face

* Fixed attempting to "scoop up" cleanable decals using a rag

* Fixed plasmaman spacehelm icon not updating when washed

Also removed a duplicated worn_overlays proc

* Fixed head icon not updating when washing lipstick

* Moved radioactive clean signal register to where it should be

* Added atom radiate VV verb for debugging

* Redesigned the CLEAN constants into a more sensible flags setup

This makes it more dynamic, cleaning apparatuses can clean more specific than just a cleaning strength.

* CLEAN_TYPE_* flags indicate a specific cleanable, such as blood, fingerprints or disease
* CLEAN_* consts consist of a combination of cleaning types to make cleaning apparatuses have a consistent behaviour on what they clean

* Fixed broken rad removal logic in showers

* Apply suggestions from code review

* Removed unneccesary bool from sink code

* Fixed wrongly named variable in turf wash

* Renamed bloody_hands to blood_in_hands
