[test] Migrate state_init_mid_circuit CHECK lines to !cc.measure_handle

PR NVIDIA#4409 widened `quake.mz` ODS to return `!cc.measure_handle`
(scalar) and `!cc.stdvec<!cc.measure_handle>` (vector). The
state-init regression test still asserted the legacy
`!quake.measure` spelling in its MLIR FileCheck blocks; update
the four affected CHECK lines.
