ACPI: Add a context argument for table parsing handlers
In preparation for drivers reusing the core table parsing
infrastructure, arrange for handlers to take a context argument. This
allows driver table parsing to wrap ACPI table entries in
driver-specific data.
The first consumer of this infrastructure is the CEDT parsing that
happens in the cxl_acpi driver, add a conditional
(CONFIG_ACPI_TABLE_LIB=y) export of a acpi_table_parse_cedt() helper for
this case.
