Commit 459f5ffa24 ("OvmfPkg/QemuKernelLoaderFsDxe: rework direct
kernel boot filesystem") has a small change in behavior: In case
there is no data the file is not created and attempts to open file
return EFI_NOT_FOUND. Old behavior was to add a zero-length file
to the filesystem.
Fix GenericQemuLoadImageLib to handle EFI_NOT_FOUND correctly for
'initrd' and 'cmdline'.

Try load shim first. In case that succeeded update the command line to
list 'kernel' first so shim will fetch the kernel from the kernel loader
file system.
This allows to use direct kernel boot with distro kernels and secure
boot enabled. Usually distro kernels can only be verified by distro
shim using the distro keys compiled into the shim binary.

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.
Since it's more standard, replace __FUNCTION__ with __func__ throughout
OvmfPkg.

Remove the QemuFwCfgLib interface used to read the QEMU cmdline
(-append argument) and the initrd size. Instead, use the synthetic
filesystem QemuKernelLoaderFs which has three files: "kernel", "initrd",
and "cmdline".

When QemuLoadKernelImage() ends successfully, the command-line blob is
not freed, even though it is not used elsewhere (its content is already
copied to KernelLoadedImage->LoadOptions). The memory leak bug was
introduced in commit ddd2be6b00 ("OvmfPkg: provide a generic
implementation of QemuLoadImageLib", 2020-03-05).

gBS->LoadImage() returning EFI_NOT_FOUND is an expected condition; it
means that QEMU wasn't started with "-kernel". Log this status code as
INFO rather than ERROR.

Implement QemuLoadImageLib, and make it load the image provided by the
QEMU_EFI_LOADER_FS_MEDIA_GUID/kernel device path that we implemented
in a preceding patch in a separate DXE driver, using only the standard
LoadImage and StartImage boot services.
