fix(NODE-6792): use driver version of isUint8Array

[nbbeeken]

Description

What is changing?

Switch from util/types to ./utils for isUint8Array

Is there new documentation needed for these changes?

No

What is the motivation for this change?

Bundlers need to add a target module for util/types for a method we already implement ourselves. No reason to cause that friction.

Release Highlight

Use isUint8Array defined in the driver rather than util/types

Some users of bundlers for next.js and our very own mongosh noticed a new import from "util/types" that would need to be supported in environments that don't have that module. We already have an internal implementation of isUint8Array so we do not need to add an import for "util/types".
