[feature] BazelDeps should allow custom path to `load_conan_dependencies`

[knzivid]

I have a repository_rule that wraps conan install ... with BazelDeps as the generator. However, conandeps/dependencies.bzl hardcodes the path to build_file as conandeps/<pkg>/BUILD. When I call load_conan_dependencies from @custom-repo//conandeps:dependencies.bzl, the build_file turns out to be incorrect.

My suggestion is to allow a conandeps_root parameter to load_conan_dependencies to allow customization.

Here's a hacky workaround
