Drop Vulkan driver tests from `tools/test/`. (#15912)

Progress on https://github.com/openxla/iree/issues/15299

This directory is for tests of the core project, so we should support
the tests on as broad a range of targets as possible. Driver-specific
tests (including ones that require specific hardware) are still useful,
but this monolithic MLIR lit test suite is not the place for them.

Without a change like this, https://github.com/openxla/iree/pull/15837
would skip the `tools/test/` test suite in the `test_all` job, since
SwiftShader is no longer used as a software implementation of Vulkan and
all Vulkan tests are skipped on CPU-only machines:
```
# Before:
iree/tools/test                                                       =  59.68 sec*proc (22 tests)

# Drop SwiftShader, without this change:
iree/tools/test                                                       =   0.27 sec*proc (1 test)

# With this change:
iree/tools/test                                                       =  49.66 sec*proc (22 tests)
```
