src: refactor TLSWrap

[jasnell]

This accomplishes a couple of things...

• Previously, TLSWrap and SSLWrap were defined separately, with SSLWrap as an abstract template class presumably with the intent of allowing it to be reused in other ways that never actually happened. Here they are collapsed and SSLWrap is eliminated entirely

• Updates and modernizes the code inside TLSWrap

While this is semver-patch, it depends on the currently semver-major #35093

Checklist

• make -j4 test (UNIX), or vcbuild test (Windows) passes

Heh, some definite failures in CI ;-) ... moving this back to draft until I can take a look

[mildsunrise]

thank you! I was going to open a PR for this same thing

[jasnell]

Awesome. It's almost done. Have to trace down a couple of failing tests that aren't exactly obvious with regards to why they're failing but it's close

[jasnell]

@mildsunrise (and others) this should be good to go now :-)

[jasnell]

Dealing with some seemingly unrelated CI failures on this. Running CI again to see what happens

[mildsunrise]

will this be backported? I initially assumed so, but it depends on a semver-major change, so 🤔

also, context for newer contributors who arrive here: SSLWrap was previously used as a common base for SecurePair (the old TLS API) and TLSWrap (the current tls.Socket API) IIRC. We completely removed SecurePair a while ago (it's now an emulation layer on top of tls.Socket), so it no longer makes sense to keep both classes.
