With the removal of mlir-vulkan-runner (as part of #73457) in
e7e3c45bc70904e24e2b3221ac8521e67eb84668, this pass no longer has to be
public (previously it had to be so the runner could use it). This commit
makes it instead only available for use by mlir-opt.
This is a recommit of 058d183980a2f334d085a46c32abded0557aa789 (#124301)
which had been reverted in 4573c857da88b3210d497d9a88a89351a74b5964 due
to a missing linker dependency on MLIRSPIRVTransforms in
mlir/test/lib/Pass/CMakeLists.txt (fixed in this commit).

**Description**
This PR adds a new option for `convert-to-spirv` pass to clone and
convert only GPU kernel modules for integration testing. The reason for
using pass options instead of two separate passes is that they both
consist of `memref` types conversion and individual dialect patterns,
except they run on different scopes. The PR also replaces the
`gpu-to-spirv` pass with the `convert-to-spirv` pass (with the new
option) in `mlir-vulkan-runner`.
**Future Plan**
Use nesting pass pipelines in `mlir-vulkan-runner` instead of adding
this option.
