c0ccdffeb7 [Concurrency] Add underscore prefixes for not yet official API.
Custom main and global executors work hasn't passed Swift Evolution yet,
so we need to avoid leaking it as API until it does.

To that end, underscore all the things.

We need to provide some of the additional functions, as stubs, for
task-to-thread model.

c20aa667f2 [Concurrency] Disable various things for task-to-thread model.
When in task-to-thread model concurrency mode, there is no `MainActor`
and we cannot use `ExecutorJob`, so disable various things.

Remove `supportsScheduling` in favour of a type-based approach.

Update the storage for `ClockTraits` to `UInt32`.

Adjust ordering of executors for `currentExecutor`.

55afa47bea [Concurrency] More work on the custom executor implementation.
Added an `-executor-factory` argument to the compiler to let you safely
specify the executors you wish to use (by naming a type that returns
them).

Also added some tests of the new functionality.

090c375b7b [Concurrency] Swift interface for custom main and global executors.
Reorganise the Concurrency code so that it's possible to completely
implement executors (both main and global) in Swift.

Provide API to choose the desired executors for your application.

Also make `Task.Sleep` wait using the current executor, not the global
executor, and expose APIs on `Clock` to allow for conversion between
time bases.
