Fails for assembly metadata containing `.`

[Khitiara]

Describe the Bug

AssemblyMetadata attributes whose keys include the . characte those generate into invalid constant names and produce compiler errors.

Steps to Reproduce

[assembly: System.Reflection.AssemblyMetadata("A.B", "")]
[assembly: System.Reflection.AssemblyMetadata("A.C", "")]

Expected Behavior

Compilation to succeed.

Version Info

ThisAssembly 1.3.1

Additional Info

Discovered when using Verify which generates a few such metadata attributes during build

Consider sponsoring @devlooped to bump the priority of this.

Otherwise, we'd gladly take a PR!

This problem also causes a failure when you include the sentry.io SDK, since that adds a Senry.ProjectDirectory AssemblyMetadata attribute.

Happy to take a PR 👌
