[PATCH v3 0/4] Fix OvmfXen boot failure due to s3 support state

["Lin, Gary (HPS OE-Linux)" <gary.lin@hpe.com>]

When using HVM Direct kernel boot with OvmfXen, it could fail at the
S3BootScript due to the inconsistency between QemuFwCfgS3Enabled()
and PcdAcpiS3Enable.

This patch series initializes PcdAcpiS3Enable in 
. Besides, QemuFwCfgS3Enabled() is
replaced with PcdAcpiS3Enable in several OVMF libraries to avoid the
potential inconsistency.

v3:
  - Update the description per Anthony's suggestion
  - Add the bugzilla links
  - Move the QemuKernelLoaderFsDxe patch out of this patch series
    and make it an independent patch
v2:
  - Amend the description and address "HVM Direct Kernel Boot"
  - Add the comment for the conditional test of QemuFwCfgS3Enabled()
  - Remove unused QemuFwCfgLib
  - Update my email address
