drm/i915/mtl/gsc: extract release and security versions from the gsc binary
The release and security versions of the GSC binary are not used at
runtime to decide interface compatibility (there is a separate version
for that), but they're still useful for debug, so it is still worth
extracting them and printing them out in dmesg.
To get to these version, we need to navigate through various headers in
the binary. See in-code comment for details.
v2: fix and improve size checks when crawling the binary header, add
comment about the different version, wrap the partition base/offset
pairs in the GSC header in a struct (Alan)
