Split the code into separate functions to allow using the

The generic code was moved to ghes_record_cper_errors(),

only a logic to fill the Generic Error Data part of the record,
as described at:

acpi_ghes_record_errors() function.

acpi: Permit OEM ID and OEM table ID fields to be changed

Qemu's ACPI table generation sets the fields OEM ID and OEM table ID
to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI
table name.

Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID
and OEM table ID for the strings "BOCHS" and "BXPC" and if they are
found, the game crashes(this may be an intentional detection
mechanism to prevent playing the game in a virtualized environment).

This patch allows you to override these default values.

The feature can be used in this manner:
qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN

The oem-id string can be up to 6 bytes in size, and the
oem-table-id string can be up to 8 bytes in size. If the string are
smaller than their respective sizes they will be padded with space.
If either of these parameters is not set, the current default values
will be used for the one missing.

Note that the the OEM Table ID field will not be extended with the
name of the table, but will use either the default name or the user
provided one.

This does not affect the -acpitable option (for user-defined ACPI
tables), which has precedence over -machine option.

ACPI: Record Generic Error Status Block(GESB) table

kvm_arch_on_sigbus_vcpu() error injection uses source_id as
index in etc/hardware_errors to find out Error Status Data
Block entry corresponding to error source. So supported source_id
values should be assigned here and not be changed afterwards to
make sure that guest will write error into expected Error Status
Data Block.

Before QEMU writes a new error to ACPI table, it will check whether
previous error has been acknowledged. If not acknowledged, the new
errors will be ignored and not be recorded. For the errors section
type, QEMU simulate it to memory section error.

ACPI: Record the Generic Error Status Block address

Generic Error Data Entries and write the error.

In order to avoid migration failure, make hardware
error table address to a part of GED device instead
of global variable, then this address will be migrated
to target QEMU.

ACPI: Build Hardware Error Source Table

This patch builds Hardware Error Source Table(HEST) via fw_cfg blobs.
Now it only supports ARMv8 SEA, a type of Generic Hardware Error
Source version 2(GHESv2) error source. Afterwards, we can extend
the supported types if needed. For the CPER section, currently it
is memory section because kernel mainly wants userspace to handle
the memory errors.

This patch follows the spec ACPI 6.2 to build the Hardware Error
Source table. For more detailed information, please refer to
document: docs/specs/acpi_hest_ghes.rst

build_ghes_hw_error_notification() helper will help to add Hardware
Error Notification to ACPI tables without using packed C structures
and avoid endianness issues as API doesn't need explicit conversion.

ACPI: Build related register address fields via hardware error fw_cfg blob

This patch builds error_block_address and read_ack_register fields
in hardware errors table , the error_block_address points to Generic
Error Status Block(GESB) via bios_linker. The max size for one GESB
is 1kb, For more detailed information, please refer to
document: docs/specs/acpi_hest_ghes.rst

Now we only support one Error source, if necessary, we can extend to
support more.
