components/liveinstall: Support all expected architectures properly

We want to be able to produce live ISOs for AArch64 and POWER with
the correct GRUB configuration. This also sets us up to handle any
quirks for each architecture platform as needed later.

This also includes a change to bump the EFI partition size for ISOs
to 30MB so everything fits.
