Older Rust toolchains didn't have the `rust-std` component for `*-unknown-uefi` targets meaning they couldn't be used for artifact dependencies. Signed-off-by: Klim Tsoutsman <klim@tsoutsman.com>

This is the first step in supporting Theseus loaded at an aribtrary address. The changes to `frame_allocator` are necessary for the frame allocator to correctly initialise when a reserved memory region overlaps with more than one reserved memory region that came before it. Reshuffling the order that the bootloader info and modules memory regions are added to the reserved memory regions revealed the problem. The PR also removes `bios` as the default feature for `nano_core` as it makes it impossible to compile for UEFI, as discussed on Discord. Signed-off-by: Klim Tsoutsman <klim@tsoutsman.com>

Older Rust toolchains didn't have the `rust-std` component for `*-unknown-uefi` targets meaning they couldn't be used for artifact dependencies. The upcoming switch to the new UEFI bootloader uses artifact dependencies on `*-unknown-uefi` targets. Signed-off-by: Klim Tsoutsman <klim@tsoutsman.com>

* Removes old assumptions/requirements that all sections
in the kernel base image are loaded into physically-contiguous
memory, especially the stack and bootloader info.
* IOW, we stop relying upon a fixed `KERNEL_OFFSET` to
calculate virtual addresses from physical addresses and vice versa;
instead, we actually translate addresses via the initial page table.
* Thus, we must obtain the address of the GDT used to boot
secondary CPUs (APs on x86) and pass it through the various
init routines so that it can be used when booting secondary CPUs.
* `PageRange` and `FrameRange` constructors will now return an
empty range if invoked with a size of 0 bytes, instead of panicking.
* The major changes in this commit is to introduce new crates that
support building Theseus for and booting it on UEFI bootloaders.
* `tools/uefi-builder` is now multi-architecture,
but aarch64 support is a WIP.
* The separate `theseus-os/uefi-bootloader` repo is a fork of
`rust-osdev/bootloader` but heavily changed to support Theseus's
needs and additional architectures.
* aarch64 is still a WIP here too.
* Currently we manually ensure that the same version of the
`uefi-bootloader*` crates are used in the Theseus workspace
and in the `tools/uefi-builder/*` crates. Ideally this would be
ensured automatically in the future.
* `uefi-builder` consists of separate, per-arch crates; we can combine
them once <rust-lang/cargo#10030> is fixed.

The bootloader is at https://github.com/theseus-os/uefi-bootloader. It will also need to be reviewed.
Depends on #785, #786, and #790. I haven't been able to properly review all the changes in this PR because it builds on top of many different PRs. Once they are merged, I'll be able to review the changes properly.
