tests: acpi: make acpi_fetch_table() take size of fetched table pointer

Currently acpi_fetch_table() assumes 32 bit size of table pointer
in ACPI tables. However X_foo variants are 64 bit, prepare
acpi_fetch_table() to handle both by adding an argument
for addr_ptr pointed entry size. Follow up commits will use that
to read XSDT and X_foo entries in ACPI tables.
