In order to support x86 verstage proper the work buffer
needs to live in cache-as-ram. However, after cache-as-ram
is torn down one still needs the verification results to
know which slot was selected. Though the platforms with
a dedicated SRAM can just use the work buffer in SRAM, the
x86 cache-as-ram platforms need a place to stash the
results. For that situation cbmem is employed. This works
because when cbmem is initialized cache-as-ram is still
enabled. The VBOOT_DYNAMIC_WORK_BUFFER case assumes
verified boot doesn't start until after cbmem is up. That
doesn't change, but it's a goal to get rid of that option
entirely once all other x86 platforms are moved over to
pre-romstage vboot.

BRANCH=None
TEST=Built and booted glados with pre-romstage verification
as well as VBOOT_DYNAMIC_WORK_BUFFER case.

There are compiler settings and interactions with other
header files that should be handled. First use __typeof__
instead of typeof because 'std' modes don't accept typeof.
The __typeof__ variant works equally well on clang. The
other change is to guard the helper macros so as not to
trigger redefinition errors.

In order to support FSP 1.1 relocation within cbfstool
the relocation code needs to be moved into commonlib.
To that end, move it. The FSP 1.1 relocation code binds
to edk2 UEFI 2.4 types unconditionally which is separate
from the FSP's version binding.

Instead of reaching into src/include and re-writing code
allow for cleaner code sharing within coreboot and its
utilities. The additional thing needed at this point is
for the utilities to provide a printk() declaration within
a <console/console.h> file. That way code which uses printk()
can than be mapped properly to verbosity of utility parameters.
