Summary Speed up dSYM generation on build.webkit.org with -gline-tables-only

We need to produce dSYM files on CI builders to have line numbers in crash logs on testers. On my machine, a full release build of WebKit with dSYM generation takes ~6 minutes longer than without (the time is split between slower compilation and slower dsymutil invocations). With -gline-tables-only AKA -gmlt, the cost is only 30 seconds, and the resulting dSYMs are also dramatically smaller (962 MB to 139 MB for WebCore). I believe that we would be getting proper crash logs with -gline-tables-only too.
