llvm_tools: Catch dup SHAs in get_upstream_patch

If a duplicate SHA is listed in get_upstream_patch.py,
we need to report this as an error and not do anything.

This commit adds this functionality, as well as
some structures to make adding this feature easier.

BUG=b:187795686
TEST=get_upstream_patch.py $args --sha $SHA --sha $SHA
