vboot: rename symbols for better consistency

Symbols prefixed with vb2_ should be reserved for internal
vboot library use.

Anything outside of that may choose some other prefix.
Here, we choose vboot_ instead.

Also, add some documentation to security/vboot/misc.h,
which provides headers for a number of different C files.
