vfs: extract 'vfs' class and related code to a new 'vfs' module (API)
The 'scmutil' is growing large (1500+ lines) and 2/5 of it is related to vfs.
We extract the 'vfs' related code in its own module get both module back to a
better scale and clearer contents.
We keep all the references available in 'scmutil' for now as many reference
needs to be updated.
