This CL adds in fuzzers for SPIRV-Cross for HLSL, GLSL, and MSL
outputs. These fuzzers live in Dawn because there is not appropriate
location in the Chromium source repo for them and it is unlikely they
would be land-able in the SPIRV-Cross repo, because it is not coupled
with Chromium's build system and thus Clusterfuzz so would be
effectively dead code. Dawn depends on this code, but it is also
integrated into the Chromium build system, so this was the best place
I could find for them
The code under fuzz unfortunately uses exceptions/aborting as its
error reporting mechanism. This is an acknowledge short coming and
there are efforts to remove this behaviour. To work around this and
reduce the number of false positives found by the fuzzers, a signal
trap has been implemented which will be removed once the code under
fuzz has been updated.
The trap replaces the existing signal handler and silencing signals
while running the code under test. This allows the code under test to
call abort() and not crash the fuzzing process. Theoretically, only
SIGABRT should need to be trapped, but something is causing the signal
from abort() to be converted to SIGSEGV when running under ASAN.
This signal trap has been tested with the fuzzing/sanitizers by
intentionally inserting bad calls that will occur after a few thousand
test cases. It was confirmed that the fuzzer detected the issue and
stops fuzzing.
The alternate to implementing this signal trap would be to turn on
exceptions for the fuzzer. This was attempted, but proved to be
fruitless due to what was reported as an ODR issue, but couldn't
couldn't be silenced. The likely underlying issue was a pre-built
library or other object being built without exceptions was causing
different versions of symbols or the exception version of the standard
library not being instrumented by ASAN. Given the majority of Chromium
eco-system turns off exceptions, fixing this issue would not be
helpful to the larger community and was looking like it would require
significant effort.

When both the vert and frag shaders have a UBO binding, the D3D12
backend was using register offset 0 for both, causing a collision,
and the wrong constant value used in one of the shaders.
The fix is to use the binding offsets computed by the BindGroupLayout,
since they know about all of the bindings, not just the ones computed
for each shader. This made it necessary to defer shader compilation
until pipeline layout creation time (as is done in the Metal backend
for similar reasons).
Finally, those bindings offsets computed by the BGL include an offset
for the CBV, UAV and SRV subgroups, so we must add the same register
offset when assigning the BaseShaderRegister to the descriptor ranges
in the PipelineLayout constructor so that they match.

d3d12::Buffer::UnmapImpl() was passing an empty range to
ID3D12Resource::Unmap(). This causes it to be a no-op when writing a
buffer. The fix is to store the entire mapped range in the Buffer,
and use it during Unmap().
Note: this doesn't seem to actually cause an issue on the D3D12 drivers I
have, so I have been unable to write a test for it. However, it does cause
an issue in RenderDoc: the buffer data appears unmodifed after the
Map/memcpy/Unmap calls. The hypothesis is that RenderDoc notices the empty
range at the API level, and leaves its shadow buffer contents unmodified.
Because I feel this change is correct regardless, I'm landing it without
a test.

These encoders are pure frontend objects and record into the

Error handling is still ew, because the "builder" mechanism we had
