[FIRRTL][LowerLayers] ref.send capture of non-passive doesn't work

Previously: #7467.

firrtl.circuit "LayersProbe" {
  firrtl.layer @A bind {}
  firrtl.module @LayersProbe(out %o: !firrtl.bundle<x flip: uint<1>>) {
    firrtl.layerblock @A {
      %0 = firrtl.ref.send %o : !firrtl.bundle<x flip: uint<1>>
    }
  }
}

circt-opt --firrtl-lower-layers --no-implicit-module --mlir-print-ir-after-failure yields:

Reproduce the failure with circt-opt --firrtl-lower-layers using the FIRRTL circuit shown in the issue, then inspect the LowerLayers path that handles firrtl.ref.send for non-passive bundles. Done means this input lowers without the firrtl.matchingconnect sized-passive-type error; no specific source file or test is named in the issue.
