[CMake] Cleanup check-lldb targets

[beanz]

Summary

This patch adds the following fixes to the check-lldb targets:

• Adds missing dependencies on lldb tools so they get built before tests execute
• Adds Ninja USES_TERMINAL to the target so that the output streams to stdout as it executes
• Uses a generator expression to find the lldb executable, this is more robust than constructing the path manually

OMG. I've been looking for this magic for forever. Praise the sun!

(Retro) Ah nice, I like the generator expression you put in there.
