Split out MemoryFileSystem (#2422)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Remove ref count for Entry in RiffFileSystem.
Free up backing Entry types (to work around Dictionary not doing this).

* Some small improvements to RiffFileSystem.

* Add testing for file systems.

* Split out MemoryFileSystem.

* Add some documentation around different FileSystems.

* Small tiry up - removing unused headers, fixing some comments.
Use StringBlob::moveCreate where appropriate.

* Small improvement to MemoryFileSystem.
Improve documentation comments a little.
