LoongArch: KVM: Add separate KVM_REQ_LBT_LOAD bit
There are different structures with FPU and LBT register restore, with
FPU the structure is vcpu::arch::fpu, with LBT the structure is vcpu::
arch::lbt. Moreover, FPU/LSX/LASX saving and restoring share the common
structure vcpu::arch::fpu.
New request bit KVM_REQ_LBT_LOAD is used for LBT register restore, and
rename KVM_REQ_AUX_LOAD with KVM_REQ_FPU_LOAD for FPU register restore.
