arm/arm64: Generalize bootblock C entry point

When we first added ARM support to coreboot, it was clear that the
    bootblock would need to do vastly different tasks than on x86, so we
    moved its main logic under arch/. Now that we have several more
    architectures, it turns out (as with so many things lately) that x86 is
    really the odd one out, and all the others are trying to do pretty much
    the same thing. This has already caused maintenance issues as the ARM32
    bootblock developed and less-mature architectures were left behind with
    old cruft.

This patch tries to address that problem by centralizing that logic
    under lib/ for use by all architectures/SoCs that don't explicitly
    opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option).
    This works great out of the box for ARM32 and ARM64. It could probably
    be easily applied to MIPS and RISCV as well, but I don't have any of
    those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and
    leave that for later cleanup.

BRANCH=None
    BUG=None
    TEST=Built Jerry and Falco, booted Oak.
