Make `UriData` more case-insensitive.

Add `isMimeType` method to `UriData` class, to allow case-insensitive
checking of the MIME type.
Add `isCharset` and `isEncoding` methods to `UriData` class,
to allow case-insensitive and alternative-encoding-name aware checking
of the MIME type "charset" parameter.
Make `UriData.fromString` and `UriData.fromBytes` recognize and omit
a "text/plain" `mimeType` even if it is not all lower-case.

Be case-insensitive in a few cases where we weren't before
(like the `charset` getter not recognizing `CHARSET=utf-8`.)
