Leonardo Francisco 29d6fea0de validity: Add new driver for Validity/Synaptics VCSFW sensors 
Add a new "validity" driver for Validity/Synaptics fingerprint sensors
that use the VCSFW protocol (as opposed to BMKT). This is iteration 1
of a multi-phase effort to bring native libfprint support to these
widely-deployed sensors found in ThinkPad T480/T480s/T580/X1 Carbon
Gen6 and many other laptops.

This initial iteration implements:
- VCSFW command/response transport layer over USB bulk endpoints
- GET_VERSION command parsing (firmware version, product ID, build)
- Synchronous probe and async open/close state machines
- Stub implementations for enroll/verify/identify (return NOT_SUPPORTED)
- umockdev replay test with real hardware capture

Supported USB IDs (VCSFW protocol):
- 138a:0090 (Validity VFS7500)
- 138a:0097 (Validity VFS5011)
- 06cb:009a (Synaptics Metallica MIS Touch)
- 138a:009d (Validity VFS7552)

These were previously (incorrectly) claimed by the synaptics driver
which uses the BMKT protocol.
