Add to_css_single_value for serializing a single PropertyDeclarationBlock
(fixes#13423)
r? @birtles
This needs to take the name of the property in question as input so that it can figure out which shorthand to serialize to (if any), since some props are part of multiple shorthands (and you need a way to distinguish between the lone value and the shorthand). I can tweak this to accept an `Option<Shorthand>` in case you only want to pass in the property name for shorthands.
In case you don't want to handle shorthands at all, we probably don't need this method at all, since you can just assert that there's a single field and serialize that.
Also, is `!important` involved here?

Minimal Win32 font platform implementation.
This uses a (very simple) Win32 API call to enumerate font
families available, and load them as byte buffers.
The font rasterization itself is done by freetype.
This gets Servo + WR + Windows working, but should be improved
by adding a proper implementation that matches fonts correctly
and also uses DirectWrite (or GDI) to handle font rasterization.

Don't log in the middle of mutating a reentrant lock
<!-- Please describe your changes on the following line: -->
Moved assertion that we are the lock owner to after the lock release. The problem is that Servo uses a reentrant lock for logging, so logging in the middle of mutating the lock is A Bad Idea.
While I was at it, I tidied up the reentrant lock code.

The cache is never effective in this case since a style attribute
adds to the set of applicable declarations.
This also avoid avoids the cache giving out-dated (incorrect) results
when `PropertyDeclarationBlock` becomes mutable in a later commit.
This is sufficient for now since CSSOM is only implemented for
`Element.style`. When StyleRule mutation is added,
some additional mechanism (such as evicting the cache) will be needed.
