lib: sbi_ecall: Generate extensions list with carray

Browse Source 
Instead of hard-coding the list of extensions in C code, use carray to
generate the list of extensions.

Using carray makes adding and removing extensions slightly cleaner. This
also paves the way for using Kconfig to disable unneeded extensions.
