regression: out of bounds read in CopyMem() in ad8692e
The CopyMem() introduced in "ad8692e avoid EFIv2 runtime services on
Apple x86 machines" copies 100 CHAR16s no matter what. NX enabled
firmware catches this and the boot breaks on those systems when the
value is smaller than that and it's up against a page boundary with a
page that's not mapped as readable.
https://uefi.org/specs/UEFI/2.10/04_EFI_System_Table.html says
that FirmwareVendor is a pointer to a NUL terminated string that
identifies the vendor that produces the system firmware for the platform.
