The first commit is #31766.

Second commit:

Use StringBytes::InlineDecoder to decode strings inputs in C++ land
instead of decoding them to buffers in JS land before passing them on
to the C++ layer. This is what the other update() methods already did.

Third commit:

Factor out the common logic into a template function.
Removes approximately six instances of copy/pasted code.

@bnoordhuis
crypto: make update(buf, enc) ignore encoding
badfa84 
Make the cipher/decipher/hash/hmac update() methods ignore the input
encoding when the input is a buffer.

This is the documented behavior but some inputs were rejected, notably
when the specified encoding is 'hex' and the buffer has an odd length
(because a _string_ with an odd length is never a valid hex string.)

The sign/verify update() methods work okay because they use different
validation logic.

Fixes: nodejs#31751

LGTM, but I am wondering if it makes sense to return a ByteSource instead of calling lambdas here? It doesn't solve the unwrapping, but the lambda obscures the control flow in my opinion. ByteSource can deal with static and dynamically allocated memory.

@tniessen I'm afraid I'm not following. If you want to open an alternate PR, I'll be happy to review it and abandon this one.

@bnoordhuis Sorry, I didn't have time to try that yet. I am okay with the change as it is, it is definitely an improvement, and if I ever end up attempting something else, we can still change it, so I would suggest to land this :-)

The second commit doesn't land cleanly on v12.x because it's on top of a semver-major change. Please open a backport PR or change the label to dont-land-on-v12.x
