Moving the HAL module shims into `iree/vm/`.

Add support for lowering mhlo.fft to Linalg. (iree-org#5450)

Only RFFT type is supported, which means the inputs are all real
numbers. Since we do not handle complex numbers in IREE and mhlo.fft
returns a complex number, we have to use mhlo.complex op to pack real
part and imaginary part together. And rely on canonicalization patterns
to fold it away. They will be folded away because we ran
`PopulateComplexLoweringPatterns` in HLOToHLOPreprocessing pass, if
there are complex number computation, mhlo.real/imag will be created.

The implementation is not FFT algorithm. It follows DFT definition to
support naive solution. See definition

Revert "[ci] Allow parallel testing on NVIDIA GPUs" (iree-org#5496)

I'm suspicious that this is the proximate cause of crashes we're seeing
while destroying the Vulkan device. We think
iree-org#2659 and
iree-org#2900 are the root cause, but
reverting for now to try to get us back to green.

Example failure, starting at the PR being reverted:

Add new max pool operations to IREE dispatch pipeline (iree-org#5469)

Allows max pool operations to propagate through the dispatch pipeline. Includes
an end-to-end test for max pool. Disabled as failing on vulkan.
