Today for x86 the _PRT() table is computed in runtime.
Under some configurations, computing the _PRT table can take more than
30 seconds and the ACPI timeout is violated.

This patchset modifies _PRT() to return a pre-computed table.

Changelog v3->v4 Thanks Igor:
- Add missing files to tests/qtest/bios-tables-test-allowed-diff.h

Changelog v2->v3 Thanks Michael:
- Code style
- Add cover letter
