WebBrowser: reduce the amount of data stored under CEF's webcache folder

A lot of the data comes from Chromium's component updater, which downloads a lot of stuff we don't want.

Memory-mapped bulk data alignment fix

Alignment was set to 1 to minimize all the padding in the memory-mapped bulk data storage & runtime memory.

Animations are memory-mapped on mobile, which violates the ACL anim sequence codec 16-byte alignment requirement. This requirement is enforced at runtime when we attempt to decompress in Debug/Development builds with an assert.
