Doug Davis d784a76fa2 Optimize .dockerignore when there are exclusions ...

Closes #20470

Before this PR we used to scan the entire build context when there were
exclusions in the .dockerignore file (paths that started with !). Now we
only traverse into subdirs when one of the exclusions starts with that dir
path.
