target/arm: Implement DBGVCR32_EL2 system register

The DBGVCR_EL2 system register is needed to run a 32-bit
EL1 guest under a Linux EL2 64-bit hypervisor. Its only
purpose is to provide AArch64 with access to the state of
the DBGVCR AArch32 register. Since we only have a dummy
DBGVCR, implement a corresponding dummy DBGVCR32_EL2.
