[PATCH v5 00/21]Change ghes to use HEST-based offsets and add support for error inject

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

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

On this version, HEST table got added to ACPI tables testing for aarch64 virt.

There are also some patch reorder to help reviewers to check the changes.

The code itself is almost identical to v4, with just a few minor nits addressed.

---
v5:
- make checkpatch happier;
- HEST table is now tested;
- some changes at HEST spec documentation to align with code changes;
- extra care was taken with regards to git bisectability.

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)
