chore: load specific bzl files instead of generic defs.bzl (bazel-contrib#2483)

rickeylev · ewianda · commit a1db6d4e9927 · 2024-12-07T15:08:59.000-05:00
Update code and examples to load the object-specific bzl files instead of the generic `defs.bzl`. This is mostly for code hygiene, but came out of trying to diagnose why Bazel 9 workspace builds kept erroing with defs.bzl somehow related. Removing the internal usages of defs.bzl doesn't seem to fully fix it, but does seem to eliminate some errors, make some progress, and narrow down what's going on. Work towards bazel-contrib#2469
