debatable: shorter name, similar to pre-existing "AWS_CRT_MEMORY_TRACING"?

Speaking of "AWS_CRT_MEMORY_TRACING", we have a hack so that it's always turned on when tests run. let's do the same thing and always turn on the crash handler

Description of changes:
Our current crash handler unintentionally catches crashes from other Python libraries that utilize native code. The stacktrace dumped by the crash handler makes it look like our fault as it contains
PyInt_initcalls at the top of the stack trace. These calls, in reality, are simply function calls made to print the stack trace and printed asPyInt_initin release mode. To address this, this PR alters the crash handler to be an opt-in feature, disabling its automatic registration. Users can enable the crash handler by setting an env variable.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
