DynamicTablesPkg: Adds ACPI EINJ Table generation support
Add an ACPI Error Injection (EINJ) table generator that uses the Configuration Manager to obtain the platform error-injection instruction entries. Ref: ACPI Specification, Section 18.6 (Error Injection—EINJ table). Co-authored-by: Varshit Pandya <varshit.pandya@arm.com> Signed-off-by: Varshit Pandya <varshit.pandya@arm.com>
