Reconcile naming: RegexGeneratorAttribute to RegexAttribute

[am11]

Re: #62105 (comment).

In the upcoming .NET 7, we have [GeneratedDllImport] and [RegexGenerator] attributes to annotate partial methods for source generators.

It would be nice to match their names at this early stage, preferably by renaming [GeneratedDllImport] to [DllImportGenerator].

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

We also have prior art shipped in .NET 6:

• JsonSerializableAttribute
• LoggerMessageAttribute

I like that the .NET 6 names that they do include Generator or Generated at all. It makes them more succinct. Should we stick to this pattern for the new source generators as much as possible?

For interop source generator, we can use this as an opportunity to switch to more platform neutral naming. Dll is Windows-specific. How about calling the attribute [LibraryImport]?

Interop source generator API proposal is tracked by #46822 (it is not in public surface yet). This issue can be used to track what if anything we want to change for RegEx.

How about calling the attribute [LibraryImport]?

More ideas: [Interop], [InteropImport], [PinvokeImport]

As Jan suggested, let's leave interop discussion in #46822. I moved the interop suggestions into that issue.
