[llvm] [CI] Add --succinct to lit args (PR #152335)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/152335

We currently log every single test that we run in premerge. This leads to gigantic logs (200k+ lines on Linux) that can be difficult to parse through. We should only indicate progress rather than explicitly logging any test that we run.

For the rare cases where someone does need to see the list of tests that run, the JUnit XML emitted by lit is available in the artifacts.
