Ability to set DebugProbes.enableCreationStackTraces using system property

[develar]

The property kotlinx.coroutines.debug.enable.creation.stack.trace is used only by AgentPremain, but not by DebugProbes.enableCreationStackTraces.

It will be great if will be no need to use DebugProbes.enableCreationStackTraces = false in the code.

Related to #3633

That is good point, we probably have to rethink that.
As well the idea of having creation stacktrace enabled by default; to be honest, I've never heard it helped anybody, but it takes quite lot of performance from debugger for marginal benefit

[qwwdfsad]

Was kindly asked to squeeze it into 1.7.2

[qwwdfsad]

We decided not to fix it in 1.7.2: it seems rather ad-hoc and the rationale is not sufficient, see: #3764 (comment)

But we also plan to disable creation stacktraces by default: #3783

[develar]

Disabling by default can take much time, not in 1.7.2, right? Anyway, I answered in that thread.

[dovchinnikov]

The main reason for this request was an (incorrect) assumption that substituting kotlin.coroutines.jvm.internal.DebugProbesKt with DebugProbesKt.bin via our own classloader implementation will automatically enable the debugging facility. It turned out, that even with the substitution, we still need to call install to start the cleaner thread, and we need to set AgentInstallationType to avoid loading byte buddy, so we might as well set enableCreationStackTraces to false in the neighbour line.

Please close this as obsolete.
