refactor!: prefix AwaitOperationConfiguration cases with Await

[xperiandri]

Proposed Changes

Part of splitting #22 into small pull requests that can be reviewed one at a time. It is the bottom of the stack and is based on main.

Unqualified cases such as Parallel 4 collided with System.Threading.Tasks.Parallel (FS1133) whenever that namespace was opened after FSharp.Control.R3. The cases now carry the Await prefix, which mirrors the Chunk prefix of ChunkConfiguration.

Types of changes

What types of changes does your code introduce to FSharp.Control.R3?
Put an x in the boxes that apply

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Checklist

Put an x in the boxes that apply. You can also fill these out after creating the PR. If you're unsure about any of them, don't hesitate to ask. We're here to help! This is simply a reminder of what we are going to look for before merging your code.

• Build and tests pass locally – 0 warnings, Fantomas is clean, and the tests that exist at this commit pass
• I have added tests that prove my fix is effective or that my feature works (if appropriate) – in test: cover the library with integration tests #22, the top of this stack
• I have added necessary documentation (if appropriate)

Further comments

Breaking change: Sequential, Drop, Switch, Parallel, SequentialParallel and ThrottleFirstLast become AwaitSequential, AwaitDrop, AwaitSwitch, AwaitParallel, AwaitSequentialParallel and AwaitThrottleFirstLast.

Tests (in #22): ProcessingOptionsTests.fs maps every case to its R3 AwaitOperation and its limit, and MapAsyncTests.fs runs mapAsync with every case.
