LibTest: Change #define-d constants into constexpr and a runtime flag

Browse source 
MAX_GENERATED_VALUES_PER_TEST is now the --randomized_runs flag:
$ ./Build/lagom/bin/TestGenerator --randomized_runs 1000

It's sometimes useful to try larger numbers for it instead of the
default of 100.

MAX_GEN_ATTEMPTS_PER_VALUE is now a constexpr. It's not usually needed
to tweak this value; we can recompile with a different value on the rare
occasion.
