Expose Cache Storage API in global window/worker scope

Expose Cache Storage API in global window/worker scope

Exposes self.caches which accesses the origin's CacheStorage instance.
Requires the --enable-experimental-web-platform-features flag, otherwise
the API is only available in Service Workers.

Okay, I think this is ready for a look, at least for landing behind a flag. The
bulk of the changes are test additions, which I roughly modeled the test
structure on what horo@ did for fetch. They're identical to the existing cache-*
ones in http/tests/serviceworker/ apart from path tweaks.

One thing we should really do before this goes out even behind a flag is the
inspector hookup, which is kind of the whole point of doing this, but that's
going to be involved as the agent/model/view now need to handle multiple origins
at a time (think: page w/ frames) like the other storage types, so I'd like to
do a follow-up inspector-only CL.

I should probably note the reviewers:

[jsbell, 2015-03-27 16:23:25]

kinuko@, michaeln@, jkarlin@, gavinp@ - please take a look?

(I should also not hit 'send' too soon, *sigh*)

Rebased the CL. Also, I need a Source/platform OWNER...

hey pdr@ - can you take a peek at the Source/platform changes? I realize they're
terrifyingly large...

I had to skim to due the large changes in Source/platform but LGTM overall.
