IMutableFileSystem::saveFileBlob (#2427)

* #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.

* Added PathKind

* * Make MemoryFileSystem not have implicit directories
* Make RelativeFileSystem only allow access to files in file system (kind of like chroot)
* Added Path::simplifyAbsolute
* Special handling for root of MemoryFileSystem
* Improvements around paths for different impls

* More improvements around RelativeFileSystem.
Special case root handling.

* Test archive serialization.
Move testinf from compression.
Remove the implicit directory test -> doesn't work on all file systems.

* Small optimization that removes need for check for a parent unless an item is being *created*.

* Add implicit path testing.

* Add support for saveFileBlob
Add testing for saveFileBlob

* Removed TemporaryFileSet
Added PlatformUtil::outputDebugMessage

* Some small improvements around RelativeFileSystem.

* Split out ImplicitDirectoryCollector so can use without requiring compression systems.

* Split out StringSliceIndexMap into own files.
