Add extra info to the README for linking building using system libbpf.
It may not be the preferred way of building, but still could be useful
in certain situations such as making changes against a local libbpf
version.

Build fails with sccache.
- Update meson-scripts/build_bpftool to support sccache. Unfortunately, this
isn't enough.
- Update README to warn about sccache and add the instruction to disable it
for buliding scx.
- Also add ⚠️ to make boot loader update step more prominent in arch
installation instruction.
Instead clone the libbpf repo at a specific hash during setup.
This is to fix an issue whereby submodules are not included
in the tarball and therefore won't be updated/fetched during
setup after unzipping the tarball.
This is to potentinally reduce issues with folks
using different versions of libbpf at runtime.
This also:
- makes static linking of libbpf the default
- adds steps in `meson setup` to fetch libbpf and make it
This reverts commit 5b9b953e3c, reversing
changes made to a7b39f24e2.
The current git submodule approach is a bit cumbersome and doesn't provide a
unified build environment for both libbpf and scx scheds. Also, the build
instruction doesn't seem to work. Let's revert it for now.
We have moved generic sched-ext status files outside of debugfs, so that
kernels without SCHED_DEBUG enabled can also access this information.
However, the README.md file is still showing the old ABI in an example.
Replace it with the new sysfs interface to avoid confusion.

- combine c and kernel-examples as it's confusing to have both
- rename 'rust-user' and 'c-user' to just 'rust' and 'c', which is simpler
- update and fix sync-to-kernel.sh
Introduce an option to enable/disable the build of all the Rust
sub-projects.
This can be useful to build scx on those systems where Rust is not
fully supported (e.g., armhf).

The root README files have some grammatical mistakes, and/or need to be
updated to not be in the context of being sent as a patch set. Update
them.
