ICU-20626 Adding valgrind to the CI tests for ICU4C.

This adds a separate CI pipeline for running valgrind on ICU4C.

The Azure Pipeline images don't have valgrind installed by default though,
so we need to install valgrind first.

We also add `--error-exitcode=1` to the valgrind options, so that any
errors found by valgrind will fail the CI build.
