The `no_std` and `no_main` attributes are only needed when we compile
the eBPF kernels for the "bpf" architecture. By feature-gating them on
the target architecture, we ensure the kernels compile just fine on a
host-architecture like x64. They won't be able to do anything
meaningfully but it is useful within the context of the larger workspace
they are embedded in as it allows `cargo build --workspace` and `cargo
test --workspace` to just work.
The aya-bpf-macros needed refactoring for:
1. Ease of testing
2. To be consistent with when we use K/V args vs. idents
3. To deprecate the use of `name` to change the exported name of a
function - we now use the symbol table.

Replace all `assert!(matches!(..))` with `assert_matches!(..)`.
Remove the now-unused build-integration-test xtask command whose logic
doesn't match that of the build-and-run command.
This commit replaces the existing RTF test runner with a simple rust
binary package called - integration-test.
integration-test depends on integration-ebpf, which contains test eBPF
code written in Rust and C. `cargo xtask build-integration-test-ebpf`
can be used to build this code and supress rust-analyzer warnings. It
does require `bpf-linker`, but that is highly likely to be available to
developers of Aya. It also requires a checkout of `libbpf` to extract
headers like bpf-helpers.h.
Since everything is compiled into a single binary, it can be run
be run locally using `cargo xtask integration-test` or remotely using
`./run.sh` which re-uses the bash script from the old test framework
to spawn a VM in which to run the tests.
