vboot: Drop argument to select slot from `vb2ex_ec_protect()`

vboot code changes has eliminated the redundant call to WP the EC-RO
region as protecting RW flash implies protecting both RO and RW flash,
so the call to protect RO is redundant. google/rex is currently takes
about 17 ms to lock down the EC.

Along with vboot changes, this patch drops argument to choose between
RO and RW slot to protect while calling into `vb2ex_ec_protect()`.
It ensures vb2ex_ec_protect() is explicitly meant for protecting RW
regions.

Additionally, update vboot submodule to upstream main to avoid the
compilation error.

Updating from commit id 35f50c3154e5:
   Fix build error when compiling without -DNDEBUG
to commit id 034907b279c9db:
   vboot_reference: eliminate redundant call to write protect EC-RO
