Description of this change

In CMake CLion, one has the option of setting a working directory under which the binary will be run. This is useful for debugging single binaries (i.e. they need no runfiles) under different contexts.

This PR adds some of that capability to the Bazel plugin by creating a setting for run configurations, and adding it to the Cidr debug process handlers.

Limitations:

• For now, this only applies to CLion debugging configurations. Other debuggers will have to be modified to use the setting, as well as non-debug configurations.
• Previously, we defaulted to the runfiles dir as the pwd if there was one. The explicit working dir has precedence over it now.

Unfortunately the setting doesn't work with gdbserver wrapper. I think it could be fixed here

intellij/clwb/src/com/google/idea/blaze/clwb/run/BlazeGDBServerProvider.java

Lines 100 to 115 in 9343e7e

	if (useRemoteDebuggingWrapper.getValue()) {
	String runUnderOption =
	String.format(
	"--run_under='%s' '%s' '%s' --once localhost:%d --target",
	"bash",
	GDBSERVER_WRAPPER.getValue(),
	gdbServerPath,
	handlerState.getDebugPortState().port);
	builder.add(runUnderOption);
	} else {
	String runUnderOption =
	String.format(
	"--run_under='%s' --once localhost:%d",
	gdbServerPath, handlerState.getDebugPortState().port);
	builder.add(runUnderOption);
	}

maybe we could just add cd <path> && there

Indeed since gdbserver is a default run type for linux I'd appreciate to see its support. Though I'm unsure if we should cd in run_under as I'd expect it to inherit cwd from bazel cwd.

edit: unfortunately cwd is not inherited, so run_under should be adjusted

Thank you for the PR! Could you please update BlazeGDBServerProvider as @tpasternak suggested?
