aya-bpf/helpers: add documentation and implement all bpf_probe_read_* wrappers
This patch adds some documentation to aya-bpf/helpers and adds documentation
for the module itself and for all of the wrappers currently defined in the module.

It also implements the rest of the bpf_probe_read_* wrappers that were missing from this
file. In the future, it probably also makes sense to add some bpf_probe_read_* wrappers
that can read directly into a map pointer, avoiding the BPF stack altogether. I'm going to
call this out of scope for this PR, but plan to submit a subsequent one that addresses
this use case.

aya-bpf/helpers: expose raw bindings through helpers::gen
Until we add another set of bpf_probe_read_* wrappers for reading into a map pointer,
users need access to the underlying bpf_probe_read helper, which is clobbered by this
module. This patch enables direct access to the underlying helpers::gen module to support
such use cases.

In my view, it would also probably make sense to just not export helpers::gen::* and force
the user to opt into helpers::gen, but this can be decided on later.
