Jonathan Rochkind 2bad7eb111 Raise more specific exception for invalid mime type from user-agent
To be able to distinguish from other kinds of `Mime::Type::InvalidMimeType` that may be raised by user or third-party code. It's only failure in parsing client-supplied content-types in ActionDispatch::Http::MimeNegotiation that should result in special handling.

This also allows third-party error handling/tracking code to specifically target the new `ActionDispatch::Http::MimeNegotiation::InvalidType` for ignoring or other special handling, separate from  `Mime::Type::InvalidMimeType`

This is a revision of #35753 in response to #37620 and discussion with @eugeneius
