staticcheck: Add per file (or generated) ignores

I would like to add ignores similar to "File-based linter directives", but in the configuration or in another file.

Background: I am dealing with generated files that violate a check (SA4003) in rare cases. When using the tool with go generate I don't have a reasonable (not hacky, or requiring a dedicated command installed) way to add a //lint:file-ignore SA4003 to the file.

For now, I have to disable the code check for my entire code base. I may be missing an obvious way to do this, but if not, it would help a lot to have that option.
