all: rely on dynamic dependency check for genproto

The genproto module incurs an unfortunate amount of dependency bloat
since it has a relatively large set of transitive dependencies.
Even though these are brought in as a weak dependency
(i.e., there is no hard code dependency on genproto),
it complicates dependency inspection since users need to vet
modules that they may not actually be using.

Avoid this weak dependency and instead rely on a dynamic check
to ensure that a sufficiently new version of genproto is used.
While it can't statically prevent old versions of genproto from being
linked into a binary, it guarantees that it will panic at init
with a helpful message on what's wrong.
