riscv/stand: pass boot hart in loader metadata

Use the RISCV_EFI_BOOT_PROTOCOL to fetch the boot hart ID, and
communicate this to the kernel via new metadata field
(MODINFOMD_BOOT_HART).

If the boot hart is not found this way, fall back to the (now
deprecated) device-tree method.

The assumption that a hart ID can be represented with a 32-bit unsigned
integer is unchanged in the kernel, but from the loader we pass the full
64-bit value. This ensures that this API won't need to change in the
future, should the wider value become necessary.

sys: make the kernel metadata pointer global

The way we got the kernel metadata pointer was by calling
preload_search_by_type with one of the following three: "elf kernel",
"elf32 kernel" and "elf64 kernel". Which one(s) we used wasn't
consistent though. Sometimes we would only try "elf kernel", and other
times we would try one of the latter two if the first failed. However,
the loader only ever sets "elf kernel" as the kernel type.

Now, the kmdp is a global, preload_kmdp, and it's initialized using
preload_initkmdp in machdep.c (or machdep_boot.c on arm/64).
preload_initkmdp takes a single boolean argument that tells us whether
not finding the kmdp is fatal or not.

Add a routine to dump boot metadata

The boot metadata (also referred to as modinfo, or preload metadata)
provides information about the size and location of the kernel,
pre-loaded modules, and other metadata (e.g. the EFI framebuffer) to be
consumed during by the kernel during early boot. It is encoded as a
series of type-length-value entries and is usually constructed by
loader(8) and passed to the kernel. It is also faked on some
architectures when booted by other means.

Although much of the module information is available via kldstat(8),
there is no easy way to debug the metadata in its entirety. Add some
routines to parse this data and allow it to be printed to the console
during early boot or output via a sysctl.

Since the output can be lengthly, printing to the console is gated
behind the debug.dump_modinfo_at_boot kenv variable as well as the
BOOTVERBOSE flag. The sysctl to print the metadata is named
debug.dump_modinfo.
