__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.

In QemuKernelLoaderFsDxeEntrypoint we use FetchBlob to read the content
of the kernel/initrd/cmdline from the QEMU fw_cfg interface. Insert a
call to VerifyBlob after fetching to allow BlobVerifierLib
implementations to add a verification step for these blobs.
This will allow confidential computing OVMF builds to add verification
mechanisms for these blobs that originate from an untrusted source
(QEMU).
The null implementation of BlobVerifierLib does nothing in VerifyBlob,
and therefore no functional change is expected.

This reverts commit efc52d67e1573ce174d301b52fa1577d552c8441.
Manually fixed conflicts in:
OvmfPkg/QemuKernelLoaderFsDxe/QemuKernelLoaderFsDxe.c
Note that besides re-exposing the kernel command line as a file in the
synthetic filesystem, we also revert back to AllocatePool instead of
AllocatePages.

Bob reports that VS2017 chokes on a tentative definition of the const
object 'mEfiFileProtocolTemplate', with the following error:
OvmfPkg\QemuKernelLoaderFsDxe\QemuKernelLoaderFsDxe.c(130):
error C2220: warning treated as error - no 'object' file generated
OvmfPkg\QemuKernelLoaderFsDxe\QemuKernelLoaderFsDxe.c(130):
warning C4132: 'mEfiFileProtocolTemplate': const object should be initialized
Let's turn the only function that relies on this tentative definition
into a forward declaration itself, and move its definition after the
external definition of the object. That allows us to drop the tentative
definition of the const object, and hopefully make VS2017 happy.

Linux v5.7 will introduce a new method to load the initial ramdisk
(initrd) from the loader, using the LoadFile2 protocol installed on a
special vendor GUIDed media device path.
Add support for this to our QEMU command line kernel/initrd loader.

On x86, the kernel image consists of a setup block and the actual kernel,
and QEMU presents these as separate blobs, whereas on disk (and in terms
of PE/COFF image signing), they consist of a single image.
So add support to our FS loader driver to expose files via the abstract
file system that consist of up to two concatenated blobs, and redefine
the kernel file so it consists of the setup and kernel blobs, on every
architecture (on non-x86, the setup block is simply 0 bytes and is
therefore ignored implicitly)

We have no need for exposing the kernel command line as a file,
so remove support for that. Since the remaining blobs (kernel
and initrd) are typically much larger than a page, switch to
the page based allocator for blobs at the same time.

Expose the existing implementation of an abstract filesystem exposing
the blobs passed to QEMU via the command line via a standalone DXE
driver.
Notable difference with the original code is the switch to a new vendor
GUIDed media device path, as opposed to a vendor GUID hardware device
path, which is not entirely appropriate for pure software constructs.
Since we are using the GetTime() runtime service in a DXE_DRIVER type
module, we need to DEPEX explicitly on gEfiRealTimeClockArchProtocolGuid.
