We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
This commit unifies the expectation format between the stepping and
LVT tests in the new debugging test harness.
Furthermore, it introduces a compression of runs of locations without
linenumbers. These default to showing as bytecode offsets from
previous line number, which overspecifies the tests: the bytecodes
chosen should not be constrained by a debugging step test.
This commit enables the execution of suspend box tests in a separate
test. It's a QoL improvement in the existing bb tests but, motivating
these changes, enables the new debugger stepping tests to step
coroutine code.
