As a bson user,
I want hex string caching to be enabled by default,
So that I do not need to opt-into a potential performance optimization.

Acceptance Criteria

Implementation Requirements

• Enable cacheHexString by default
• Ensure the cached hex string is lazily populated (instantiating an object id with a non-string constructor argument should not construct a hex string to cache).
• Ensure deep equality of object ids is unaffected (this is already true).
• Remove the hex string cache WeakMap in favor of JS private properties
