OvmfPkg/LoongArchVirt: Fix ResetSystemLibConstructor signature and header

The ResetSystemLibConstructor was incorrectly declared with EFI_API and
a UEFI driver entry point signature (ImageHandle, SystemTable), but it
is actually a library constructor that should use EFIAPI and take no
arguments (VOID) as per EDK2 library constructor conventions.

This mismatch caused compilation errors when enabling TPM2 support
for LoongArchVirt.

- Add missing <IndustryStandard/Acpi.h> include
- Replace EFI_API with EFIAPI
- Change constructor signature from
  (IN EFI_HANDLE ImageHandle, IN EFI_SYSTEM_TABLE *SystemTable)
  to (VOID)
