Dynamic execution ignores exec constraints

[keith]

Description of the bug:

We have a test target like this:

foo_test(
   name = "foo",
   exec_group_compatible_with = {
       "test": ["//:some_gpu_requirement"],
   }
   ...
)

When developers compile on CPU machines, where the host platform does not have the //:some_gpu_requirement, but a register remote execution platform does have the constraint, I believe dynamic execution ignores this difference, and still attempts to race the test locally, even though it doesn't match the requirements.

I can probably workaround this by disabling dynamic execution for the TestRunner mnemonic, but I'm still surprised by this behavior.

If I aquery the test I can see the execution platform is set correctly, but then you can see it still runs locally with --debug_spawn_scheduler
