AllocateUninitializedJSArrayWithElements into the method.
Prior to the change, if the caller forgets to handle empty case on
their side, AllocateUninitializedJSArrayWithElements would allocate a
new empty FixedArray rather than return the canonical one. This refactor
shifts the burden of canonicalization from the callers to
AllocateUninitializedJSArrayWithElements.

Previously the KeyAccumulator incorrectly reused the filter properties when
collecting the keys of a proxy target. This led to incorect behavior where for
instance non-enumerable properties were filtered too early.

Migrate the Object.keys builtin to the CodeStubAssembler and
use the enum cache backing store whenever it is available. This
gives a nice speedup of 1.5x to 2x when using Object.keys on fast-mode
objects that have (or can have) an enum cache.
