Rollup merge of #88452 - xu-cheng:vecdeque-from-array, r=m-ou-se ...

VecDeque: improve performance for From<[T; N]>

Create `VecDeque` directly from the array instead of inserting items one-by-one.

Benchmark
```
./x.py bench library/alloc --test-args vec_deque::bench_from_array_1000
```

* Before
```
test vec_deque::bench_from_array_1000                    ... bench:       3,991 ns/iter (+/- 717)
```

* After
```
test vec_deque::bench_from_array_1000                    ... bench:         268 ns/iter (+/- 37)
```
