[issue41849] Support reading long lines with io._WindowsConsoleIO

[Steve Dower]

I'm in favour of this change in principle, but would want to look at the PR closely.

The biggest risk here is that we have to emulate GNU readline for compatibility, which severely limits the data that can be passed through, and also forces multiple encoding/decoding passes. It would be nice to be able to bypass this in cases where nobody is using it, though since so many host applications use hooks there'll likely only be a benefit to people at the plain console...
