* Hide scheduler from RunOnFrameworkThread
Creating new tasks via Task.Run and alike would fetch the current
scheduler, which we do not want in case of running stuff from the
framework thread. Change is to prevent the standard library from seeing
the "current scheduler". If one wants to use `await` with an async
function to be run in the framework thread, one can use
`RunOnFrameworkThreadAwaitable` instead now.
* TaskSchedulerWidget: test better stuff
* TaskSchedulerWidget: add freeze tests
* More comments
* Make TaskFactory a getter method instead of property to avoid bad suggestions
* Why are there stuff still not pushed
* Add IInternal/PublicDisposableService
Plugins are exposed interfaces that are not inherited from
`IDisposable`, but services implementing plugin interfaces often
implement `IDisposable`. Some plugins may try to call
`IDisposable.Dispose` on everything provided, and it also is possible to
use `using` clause too eagerly while working on Dalamud itself, such as
writing `using var smth = await Service<SomeService>.GetAsync();`. Such
behaviors often lead to a difficult-to-debug errors, and making those
services either not an `IDisposable` or making `IDisposable.Dispose` do
nothing if the object has been loaded would prevent such errors. As
`ServiceManager` must be the only class dealing with construction and
disposal of services, `IInternalDisposableService` has been added to
limit who can dispose the object. `IPublicDisposableService` also has
been added to classes that can be constructed and accessed directly by
plugins; for those, `Dispose` will be ignored if the instance is a
service instance, and only `DisposeService` will respond.
In addition, `DalamudPluginInterface` and `UiBuilder` also have been
changed so that their `IDisposable.Dispose` no longer respond, and
instead, internal functions have been added to only allow disposal from
Dalamud.
* Cleanup
* Postmerge fixes
* More explanation on RunOnFrameworkThread(ClearHooks)
* Mark ReliableFileStorage public ctor obsolete
