hw/loongarch: Rename LoongArchMachineState with LoongArchVirtMachineState

Rename LoongArchMachineState with LoongArchVirtMachineState, and change
variable name LoongArchMachineState *lams with LoongArchVirtMachineState
*lvms.

Rename function specific for virtmachine loongarch_xxx()
with virt_xxx(). However some common functions keep unchanged such as
loongarch_acpi_setup()/loongarch_load_kernel(), since there functions
can be used for real hw boards.
