This patch ensures `chromeos_get_factory_config()` returns an
unsigned integer value because factory config represents
bit-fields to determine the Chromebook Plus branding.
Additionally, introduced safety measures to catch future
"factory_config" bit-field exhaustion.

This patch implements an API which relies on the
chromeos_get_factory_config() function to retrieve the factory
config value.
This information is useful to determine whether a ChromeOS device
is branded as a Chromebook Plus based on specific bit flags:
- Bit 4 (0x10): Indicates whether the device chassis has the
"chromebook-plus" branding.
- Bits 3-0 (0x1): Must be 0x1 to signify compliance with
Chromebook Plus hardware specifications.

Even though this SoC is called 'Genoa', the openSIL implementation and
the corresponding coreboot integration is only a proof of concept that
isn't fully featured, has known limitations and bugs, and is not meant
for or ready to being productized. Adding the proof of concept suffix to
the name should point this out clearly enough so that no potential
customer could infer that this might be a fully functional and supported
implementation which it is not.

To quote its repo[0]: Wuffs is a memory-safe programming language (and
a standard library written in that language) for Wrangling Untrusted
File Formats Safely. Wrangling includes parsing, decoding and encoding.
It compiles its library, written in its own language, to a C/C++ source
file that can then be used independently without needing support for
the language. That library is now imported to src/vendorcode/wuffs/.
This change modifies our linters to ignore that directory because
it's supposed to contain the wuffs compiler's result verbatim.
Nigel Tao provided an initial wrapper around wuffs' jpeg decoder
that implements our JPEG API. I further changed it a bit regarding
data placement, dropped stuff from our API that wasn't ever used,
or isn't used anymore, and generally made it fit coreboot a bit
better. Features are Nigel's, bugs are mine.
This commit also adapts our jpeg fuzz test to work with the modified
API. After limiting it to deal only with approximately screen sized
inputs, it fuzzed for 25 hours CPU time without a single hang or
crash. This is a notable improvement over running the test with our
old decoder which crashes within a minute.
Finally, I tried the new parser with a pretty-much-random JPEG file
I got from the internet, and it just showed it (once the resolution
matched), which is also a notable improvement over the old decoder
which is very particular about the subset of JPEG it supports.
In terms of code size, a QEmu build's ramstage increases
from 128060 bytes decompressed (64121 bytes after LZMA)
to 172304 bytes decompressed (82734 bytes after LZMA).

Having a separate romstage is only desirable:
- with advanced setups like vboot or normal/fallback
- boot medium is slow at startup (some ARM SOCs)
- bootblock is limited in size (Intel APL 32K)
When this is not the case there is no need for the extra complexity
that romstage brings. Including the romstage sources inside the
bootblock substantially reduces the total code footprint. Often the
resulting code is 10-20k smaller.
This is controlled via a Kconfig option.
TESTED: works on qemu x86, arm and aarch64 with and without VBOOT.
