feat(node): Vendor cookie module

[timfish]

Ref #9199

This PR vendors the cookie module. I simplified the code a little since we don't use the options parameter.

Ehhhh, we actually use cookie as well, so now we basically have 2 copies of almost the same code? Was this really necessary?

@alfaproject please see https://develop.sentry.dev/sdk/philosophy/#dependencies-cost - we try to avoid using deps in our SDK as much as possible.

Except in this case you didn't avoid anything, you literally cloned it. Pretty much every Express user out there will have this code duplicated. Oh well, thanks for the info
