Needs to be supported in nac3artiq + nac3standalone

Need to find a way to annotate it in nac3artiq. How about something like

class Foo:
   MY_ATTR0 = 32 # host only
   MY_ATTR1: int32 = 32  # host only
   MY_ATTR2: KernelInvariant[int32] = 32  # accessible to the kernel
   MY_ATTR3: Kernel[int32] = 32  # do we want to support this? OK if such attributes are immutable

Example code (nac3artiq) that should work but does not:

from artiq.experiment import *
from artiq.coredevice.core import Core


@nac3
class XXX:
    TEST: KernelInvariant[int32] = 32

@nac3
class NAC3Devices(EnvExperiment):
    core: KernelInvariant[Core]

    YYY: KernelInvariant[int32] = 32

    def build(self):
        self.setattr_device("core")

    @kernel
    def run(self):
        print_rpc(XXX.TEST)
        print_rpc(self.YYY)
        print_rpc(NAC3Devices.YYY)
