Reland "2lib/2api: Deprecate vb2ex_ec_trusted()"

This reverts commit b9644352d7717d4f564be90aac6c41bef583d930.

Reason for revert: We can try another reland after the coreboot
CL https://review.coreboot.org/c/coreboot/+/58253 is
downstreamed and the guybrush psp_verstage.bin is signed again.

> > coreboot will support check the EC_IN_RW during verstage_main(), which
> > performs the equivalent tasks as vb2ex_ec_trusted().
> >
> > In the previous CL, we remove the check of vb2ex_ec_trusted(), so the
> > whole implementation of this function among vboot_reference and
> > depthcharge could be deprecated and removed.
