[PATCH v4 00/14] Change ghes to use HEST-based offsets and add support for error inject

[Mauro Carvalho Chehab]

Now that the ghes preparation patches were merged, let's add support
for error injection.

On this series, the first 6 patches chang to the math used to calculate offsets at HEST
table and hardware_error firmware file, together with its migration code. Migration tested
with both latest QEMU released kernel and upstream, on both directions.

The next patches add a new QAPI to allow injecting GHESv2 errors, and a script using such QAPI
   to inject ARM Processor Error records.

---
v4:
- added an extra comment for AcpiGhesState structure;
- patches reordered;
- no functional changes, just code shift between the patches in this series.

v3:
- addressed more nits;
- hest_add_le now points to the beginning of HEST table;
- removed HEST from tests/data/acpi;
- added an extra patch to not use fw_cfg with virt-10.0 for hw_error_le

v2: 
- address some nits;
- improved ags cleanup patch and removed ags.present field;
- added some missing le*_to_cpu() calls;
- update date at copyright for new files to 2024-2025;
- qmp command changed to: inject-ghes-v2-error ans since updated to 10.0;
- added HEST and DSDT tables after the changes to make check target happy.
  (two patches: first one whitelisting such tables; second one removing from
   whitelist and updating/adding such tables to tests/data/acpi)
