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.
