[llvm] [Github] Add Timeouts to Premerge Jobs (PR #164038)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/164038

The premerge jobs currently use the default timeouts. If something ends up hanging, they run for the full six hours. Given our jobs never actually take six hours other than when something hangs, we should set the timeouts lower to not use up machine capacity when something does go wrong. These limits were currently chosen conservatively, being a decent amount above the maximum run times I have seen over the past couple months, excluding six hour timeouts.
