Adding simplified HAL dispatch methods. (#18189)

These combine push constants and push descriptor sets into the dispatch
calls as in practice we have a near 1:1 relationship anyway. Pipeline
layouts are still used in HAL interfaces to allow the compiler to map
the information but are otherwise not used by the new ops.

The `--iree-hal-experimental-dispatch2` flag enables emitting the new
ops. Since executables no longer require pipeline layouts in this
simplified model the `--iree-hal-experimental-executable-create2` flag
can be used to stop passing them; targets that support dispatch2 will
ignore them if provided. Future changes will start to add support on
targets for the simplified bindings and then remove the existing
pipeline layout-based binding model as a breaking ABI change.

Current target status:
* [x] Local/CPU: executable-create2 and executable-dispatch2 supported
(backward compat)
* [x] CUDA: executable-dispatch2 supported (backward compat)
* [x] HIP: executable-dispatch2 supported (backward compat)
* [x] Metal: executable-dispatch2 supported (backward compat)
* [x] Vulkan: executable-dispatch2 supported (backward compat)
* [x] WebGPU: executable-dispatch2 supported (backward compat)

Reworking the CUDA/HIP/Metal/Vulkan/WebGPU flatbuffers to support
executable-create2 will be done in a follow-up.

Progress on #18154.
