Improved RCDs (#22799)

* Initial radial menu prototyping for the RCD

* Radial UI buttons can send messages to the server

* Beginning to update RCDSystem

* RCD building system in progress

* Further updates

* Added extra effects, RCDSystem now reads RCD prototype data

* Replacing tiles is instant, multiple constructions are allowed, deconstruction is broken

* Added extra functionality to RadialContainers plus documentation

* Fixed localization of RCD UI strings

* Menu opens near cursor, added basic RCD

* Avoiding merge conflict

* Implemented atomized construction / deconstruction rules

* Increased RCD ammo base charges

* Moved input context definition to content

* Removed obsoleted code

* Updates to system

* Switch machine and computer frames for electrical cabling

* Added construction ghosts

* Fixed issue with keybind detection code

* Fixed RCD construction ghost mispredications

* Code clean up

* Updated deconstruction effects

* RCDs effects don't rotate

* Code clean up

* Balancing for ammo counts

* Code clean up

* Added missing localized strings

* More clean up

* Made directional window handling more robust

* Added documentation to radial menus and made them no longer dependent on Content

* Made radial containers more robust

* Further robustness to the radial menu

* The RCD submenu buttons are only shown when the destination layer has at least one children

* Expanded upon deconstructing plus construction balance

* Fixed line endings

* Updated list of RCD deconstructable entities. Now needs a component to deconstruct instead of a tag

* Bug fixes

* Revert unnecessary change

* Updated RCD strings

* Fixed bug

* More fixes

* Deconstructed tiles/subflooring convert to lattice instead

* Fixed failed tests (Linux doesn't like invalid spritespecifer paths)

* Fixing merge conflict

* Updated airlock assembly

* Fixing merge conflict

* Fixing merge conflict

* More fixing...

* Removed erroneous project file change

* Fixed string handling issue

* Trying to fix merge conflict

* Still fixing merge conflicts

* Balancing

* Hidden RCD construction ghosts when in 'build' mode

* Fixing merge conflict

* Implemented requested changes (Part 1)

* Added more requested changes

* Fix for failed test. Removed sussy null suppression

* Made requested changes - custom construction ghost system was replaced

* Fixing merge conflict

* Fixed merge conflict

* Fixed bug in RCD construction ghost validation

* Fixing merge conflict

* Merge conflict fixed

* Made required update

* Removed lingering RCD deconstruct tag

* Fixing merge conflict

* Merge conflict fixed

* Made requested changes

* Bug fixes and balancing

* Made string names more consistent

* Can no longer stack catwalks
