mb/google/nami: Add VBT blobs and include them in cbfs

Add vbt files for nami variants and select Kconfig option
to utilize them. The default vbt is automatically added
by the Kconfig selection and so does not need to be
specified in the makefile with the others.

Test: boot vayne and akali nami variants, verify
display functional and correct vbt loaded.
