chore: fix JavaScript lint errors (issue #11559)

Replace three `new Array( len/8 )` + zero-fill-loop patterns with an
empty array-literal plus `push` loop in
`lib/node_modules/@stdlib/assert/has-sharedarraybuffer-support/test/test.js`
to satisfy the `stdlib/no-new-array` rule. The Mock() helpers produce
identical output; only the allocation strategy changes.

Resolves #11559
