Make runfiles conflicts fail the build.

Previously, runfiles conflicts would print an ERROR message and then allow the build to continue, resolving the conflict in an arbitrary way.

Most of this CL is churn to allow the runfiles mapping computation methods to raise ExecException. The only interesting changes are in Runfiles.java, RunfilesTest.java, and SkylarkRuleImplementationFunctionsTest.java.

Fixes https://github.com/bazelbuild/bazel/issues/4965.

Closes #5814.
