Removed the uses of the Legacy FileWrapper classes from the source code. The wrappers were creating an additional layer of indirection/wrapping, as the Env already has a FileSystem.

Moved the Custom FileWrapper classes into the CustomEnv, as these classes are really for the private use the the CustomEnv class.

I guess this file should be removed from the PR?

LGTM. I think this can be merged once #7858 is merged. Any idea why the clang-analyze test is failing?

And remove LegacyFileSystem from public consumption.
Make WinEnv into a CompositeEnv
Made all of the uses of the Legacy and Composite  FileWrapper classes private.  Since all Env objects have a FileSystem already, most of the Legacy wrapping was adding an extra layer of wrapping.  The Composite classes were already "private" to the CompositeEnv and just needed relocated into a source file.
