[3.13] gh-124096: Enable REPL virtual terminal support on Windows (GH-124119) (GH-133457)

To support virtual terminal mode in Windows PYREPL, we need a scanner
to read over the supported escaped VT sequences.

Windows REPL input was using virtual key mode, which does not support
terminal escape sequences. This patch calls `SetConsoleMode` properly
when initializing and send sequences to enable bracketed-paste modes
to support verbatim copy-and-paste.
(cherry picked from commit a65366ed87)
