Semantic Versions for 5.3

[SDGGiesbrecht (Jeremy David Giesbrecht)]

Several packages in the Swift namespace have no semantic versions that work with Swift 5.3 yet.

May I request that those with the necessary access create them?

I have toyed with pointing at branches, and these appear to be the only necessary changes:

1. llbuild
   1. create version 0.3.0 at swift-5.3-RELEASE
2. SwiftPM (@abertelrud?)
   1. start at swift-5.3-RELEASE
   2. specify dependencies
      • llbuild 0.3.0
      • swift-tools-support-core 0.1.10
   3. create version 0.7.0
3. SwiftSyntax (@akyrtzi?)
   1. create version 0.50300.0 at swift-5.3-RELEASE
4. swift-format (@allevato?)
   1. start at swift-5.3-branch
   2. specify dependencies
      • SwiftSyntax 0.50300.0
   3. create version 0.50300.0

Apologies if you have already started.

SwiftSyntax (@akyrtzi?)

1. create version 0.50300.0 at swift-5.3-RELEASE

This is done

swift-format (@allevato?)

1. start at swift-5.3-branch
2. specify dependencies
   • SwiftSyntax 0.50300.0
3. create version 0.50300.0

swift-format 0.50300.0 is now up.

For the remaining repositories, I have tagged 0.50300.0 in some stub forks (llbuild, swift‐package‐manager) which anyone can use until the official repositories have tags of their own.
