refactor(transformer/class-properties): duplicate_object_twice method

[overlookmotel]

Follow-up after #7664.

Generalize duplicate_object to produce however many duplicates are required. Use it in transform_expression_to_wrap_nullish_check.

This should be slightly more efficient, and will make it fool-proof if we expand duplicate_object later to handle other Expression types.

It's pretty crazy that Rust makes you use unsafe code to do something as simple as creating an array with all items initialized from a function. This should be in the standard library.
