Log Message:
-----------
OvmfPkg/QemuKernelLoaderFsDxe: rework direct kernel boot filesystem
Split KERNEL_BLOB struct into two:
* One (KERNEL_BLOB_ITEMS) static array describing how to load (unnamed)
blobs from fw_cfg.
* And one (KERNEL_BLOB) dynamically allocated linked list carrying the
data blobs for the pseudo filesystem.
Also add some debug logging. Prefix most functions with 'QemuKernel'
for consistency and easier log file grepping. Add some small helper
functions.
This refactoring prepares for loading blobs in other ways.
No (intentional) change in filesystem protocol behavior.

OvmfPkg/QemuKernelLoaderFsDxe: allow longer file names
QEMU_FW_CFG_FNAME_SIZE is 56. 'etc/boot/' prefix is minus 9. Add one
for the terminating '\0'. Effective max size is 48.

OvmfPkg/QemuKernelLoaderFsDxe: drop bogus assert
Triggers when trying to get root directory info.
Reproducer:
* Use qemu -kernel with something edk2 can not load.
* When dropped into the efi shell try inspect the file system.

OvmfPkg/QemuKernelLoaderFsDxe: don't quit when named blobs are present
Allows to use the qemu kernel loader pseudo file system for other
purposes than loading a linux kernel (or efi binary). Passing
startup.nsh for EFI shell is one example.

OvmfPkg/X86QemuLoadImageLib: support booting via shim
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.

OvmfPkg/X86QemuLoadImageLib: make legacy loader configurable.
Add the 'opt/org.tianocore/EnableLegacyLoader' FwCfg option to
enable/disable the insecure legacy linux kernel loader.
For now this is enabled by default. Probably the default will be
flipped to disabled at some point in the future.
Also print a warning to the screen in case the linux kernel secure
boot verification has failed.
