[idd] input: add virtual HID driver

Build LGInput as an independent UMDF driver with its own entry point,
service, tracing, and binary.

Expose absolute pointer, relative mouse, and keyboard collections with a
guarded report queue.

Keep LGIdd as the startup and deployment project. Give it a non-linking
build/package dependency on LGInput so F5 stages both driver stacks and
installs them together through LGIddInstall, while the two UMDF binaries
remain independent for future IPC.

Stage both DLLs for the NSIS installer, retain the WDK UMDF remote-debug
startup attachment, and move CSRWLock into LGCommon for the input
driver's report queue.
