  [MIR] Serialize virtual register flags (#110228)

[MIR] Serialize virtual register flags

This introduces target-specific vreg flag serialization. Flags are represented as `uint8_t` and the `TargetRegisterInfo` override provides methods `getVRegFlagValue` to deserialize and `getVRegFlagsOfReg` to serialize.
