bors fabf502a7a Auto merge of #87168 - the8472:flatten-len, r=scottmcm
implement TrustedLen for Flatten/FlatMap if the U: IntoIterator == [T; N]

This only works if arrays are passed directly instead of array iterators
because we need to be sure that they have not been advanced before
Flatten does its size calculation.

resolves #87094
