This allows us to get rid of another mime-type list in the codebase.
To do so, the `get_description_from_mime_type` function is introduced in
this patch.
We used to have two separate lists for mime-type detection, one for
detection based on the file extension, and the other one for detection
based on byte sniffing.
This list also contains a general description that will be of use in
`file.cpp`.
To create this list, I had to fill in some gaps as the two lists started
to diverge.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This attempts to guess the mime-type from a given set of bytes from the
start of a file. It only supports a few well-defined patterns for now,
but it's a start!
