Some mainboards need a mainboard-specific mechanism to access option
values. Allow mainboards to implement the option API. Also, add some
documentation about the current option API, and describe when should
one reimplement the option API in mainboard code: only when the code
is mainboard-specific to comply with externally-imposed constraints.

Sooner or later, some board was going to need extra FW_CONFIG bits for
a field that was already in production, so this patch adds support for
adding extra (unused) bits to a field.
The extra are appended via a syntax like:
`field FIELD_NAME START0 END0 | START1 END1 | START2 END2 ...`
and the suffixed bits are all treated as if they are contiguous when
defining option values.

We all knew this was coming, 32 bits is never enough. Doing this early
so that it doesn't affect too much code yet. Take care of every usage of
fw_config throughout the codebase so the conversion is all done at once.

Implements fit_payload_arch for the arm (aarch32) architecture, so that
FIT images can be used. The implementation is very similar to the
existing implementations for arm64 and riscv, and has mostly been
lifted from these other ports.
TEST: Booted Beaglebone Black (in progress port, to be submitted soon!)
with a FIT image containing a 5.4 kernel, dtb and initramfs.

This change introduces a new top-level interface for interacting with a
bitmask providing firmware configuration information.
This is motivated by Chromebook mainboards that need to support multiple
different configurations at runtime with the same BIOS. In these
devices the Embedded Controller provides a bitmask that can be broken
down into different fields and each field can then be broken down into
different options.
The firmware configuration value could also be stored in CBFS and this
interface will look in CBFS first to allow the Embedded Controller value
to be overridden.
The firmware configuration interface is intended to easily integrate
into devicetree.cb and lead to less code duplication for new mainboards
that make use of this feature.
BUG=b:147462631
TEST=this provides a new interface that is tested in subsequent commits
