Allow code elsewhere in the system to check whether the ACPI GHES
table is present, so it can determine whether it is OK to try to
record an error by calling acpi_ghes_record_errors().
(We don't need to migrate the new 'present' field in AcpiGhesState,
because it is set once at system initialization and doesn't change.)

Generic code in target/arm wants to call acpi_ghes_record_errors();
provide a stub version so that we don't fail to link when
CONFIG_ACPI_APEI is not set. This requires us to add a new
ghes-stub.c file to contain it and the meson.build mechanics
to use it when appropriate.
