Chris Tate 71deae1acf Read dyn array elements and lengths by number without a key string ...

Indexing a value typed unknown with a number, such as `items[i]` on an
unknown[], converted the index to a string and looked it up as a property
key, and `items.length` read the property by name and boxed the result.
In a loop over an unknown[] that costs a string allocation, a key parse
and a number box per iteration.

The computed-read and `length` helpers the class dispatch generates are
now marked for a numeric fast path. A call to one of them with a number
index first asks the runtime for the element of a dyn array or a live
array capsule (scr_dyn_index_get), and a `length` read checked as a number
asks for the array's length (scr_dyn_array_length). The key string is
built and the helper runs only when the receiver is anything else, so
objects, strings, proxies, class instances, holes and out-of-range or
non-index numbers keep the keyed path.
