Raphael Isemann f9ad112770 [lldb] Speed up TestValueObjectRecursion by making it a no_debug_info_test
This is one of the most expensive tests and runs for nearly half a minute on
my machine. Beside this test just doing a lot of work by iterating 15k times on
one ValueObject (which seems to be the point), it also runs this for every
debug info variant which doesn't seem relevant to just iterating ValueObject.

This marks it as no_debug_info_test to only run one debug info variation
and cut down the runtime to around 7 seconds on my machine.
