Use Gradle dependency dynamic versioning (#1612)

* Use Gradle dependency dynamic versioning

Use dynamic versioning for Gradle dependencies when possible.
Please refer to go/dr-dependency-upgrade for more information about the
automation plan.

This PR calls out all dependencies that must be pinned to specific
versions for various reasons. The remaining ones are converted to
open-ended version ranges ("[version_str,)").
