I decided to just use more nesting here rather than the break pattern. It's not necessarily "better", just a matter of personal preference.

.as_generator_expr() lets us avoid the clone.

…matches `C416` (#10596) ## Summary <!-- What's the purpose of the change? What does it do, and why? --> Similar to #10419, there was a case where there is a collision of C401 and C416 (as discussed in #10101). Fixed this by implementing short-circuit for the comprehension of the form `{x for x in foo}`. ## Test Plan <!-- How was it tested? --> Extended `C401.py` with the case where `set` is not builtin function, and divided the case where the short-circuit should occur. Removed the last testcase of `print(f"{ {set(a for a in 'abc')} }")` test as this is invalid as a python code, but should I keep this?

Summary
Short-circuit implementation mentioned in #10403.
I implemented this by extending C400:
UnnecessaryGeneratorListhave information of whether the the short-circuiting occurred (to put diagnostic)unnecessary_generator_listfunction.Please give me suggestions if you think this isn't the best way to handle this :)
Test Plan
Extended
C400.pya little, and written the cases where:liste.g.list(x for x in range(3))->list(range(3))liste.g.list(2 * x for x in range(3))->[2 * x for x in range(3)]listfunction is not built-in, and should not modify the code in any way.
