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

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 |
