Solution Entities (#21916)

* Creates Content.Shared.Chemistry.Solutions
Copies Solution class to new namespace
Obsoletes old Solution class

* Switches over to the Solutions.Solution Solution

* Creates Content.Shared.Chemistry.Containers
Copies relevant components/systems to the new namespace
Obsoletes old versions

* Switches over to the Containers.XYZ namespace

* Creates SolutionSystem and obsoletes old SolutionContainerSystem methods

* Start using SolutionSystem for Solution manipulation

* EnumerateSolutions

* Move TryGetMixableSolution

* Move EnsureSolution to Server

* Create Solution Entities

* Stop using obsolete solution system methods

* Fix prototype component tests

* Add using ..Audio.Systems; back

* Wrap solution container slots in ContainerSlots

* Actually add the slot to the solution container map

* Dirty SolutionContainerComponent when ensuring solutions

* Revert namespace changes

* Remerge SolutionSystem and SolutionContainerSystem

* SolutionContainerManagerComponent refactor

* Avoid wrapping necessary code in DebugTools.Assert as it is removed when compiling for release

* Readd examine reagent sorting

* Fix errors

* Poke tests

* Fix solution names not being applied

* Fix WoolyComponent including statement

* Fix merge skew

* Fix compile errors

* Make reactions use solntities

* Reindent solution class namespace

* Field attribute changes

* AutoGenerateComponentState for SolutionContainerComponent

* SolutionContainerComponent -> ContainedSolutionComponent

* ref ReactionAttemptEvent

* Denetwork preinit solutions

* Misc 1

* Nullable TryGetSolution out vars

* Cache associated solutions

* Fix merge skew

* Use explicit regions in SharedSolutionContainerSystem.Capabilities

* Add debug assert

* Use explicit regions in SharedSolutionContainerSystem.Relay + ref SolutionContainerChangedEvent

* ContainedSolutionComponent.Name -> ContainedSolutionComponent.ContainerName

* SolutionComponent doc comments

* Implicit DataField names and property purge

* ReagentEffect DataField names

* Local variables for readability

* Sort using statements + Entity<T> event handlers

* Fix compile erros

* Fix compile errors
