Alexander Usyskin 741eeabb7c mei: late_bind: add late binding component driver
Introduce a new MEI client driver to support Late Binding firmware
upload/update for Intel discrete graphics platforms.

Late Binding is a runtime firmware upload/update mechanism that allows
payloads, such as fan control and voltage regulator, to be securely
delivered and applied without requiring SPI flash updates or
system reboots. This driver enables the Xe graphics driver and other
user-space tools to push such firmware blobs to the authentication
firmware via the MEI interface.

The driver handles authentication, versioning, and communication
with the authentication firmware, which in turn coordinates with
the PUnit/PCODE to apply the payload.

This is a foundational component for enabling dynamic, secure,
and re-entrant configuration updates on platforms like Battlemage.
