Mime Type for DTS:X streams should be "vnd.dts.uhd;profile=p2"

[cedricxperi]

As mentioned in one of the comments in the following pull requests, #9162, the correct mimetype for streams with "dtsx" should be "vnd.dts.uhd;profile=p2" instead of "vnd.dts.uhd". This is defined in https://www.iana.org/assignments/media-types/audio/vnd.dts.uhd

Assigning to @kim-vde as the reviewer of #9163 where this MIME type was added to MimeTypes.java (merged in 8e29e76).

CC @ProtoScott as the author of #9163 and #9162 and @krocard who pointed out the profile=p2 thing in #9162.

The fix will be included in the upcoming 2.15.1 release.
