enable ENABLE_VIRTUAL_TERMINAL_INPUT on Windows to enable bracketed paste when supported

[KristofferC]

Should fix #53763. Making a PR so I can test the build.

This does not seem to improve pasting "julia> 5+5" for me - this PR behaves as before.

In fact, I haven't been able to find any behavioral difference in Windows Terminal w/ this PR - including what I believe are bracketed paste sequences. I might be missing a test case, of course.

Looks like something is still resetting the console mode:

julia> enable_virtual_terminal_input(); get_input_console_mode()
0x00000207

julia> get_input_console_mode()
0x00000007

Reset is happening in:

Looks like we may want UV_TTY_MODE_RAW_VT but we'd need a libuv update: libuv/libuv@843b64f

Ah yes, I recall mentioning that in #53763

Something seems to keep resetting the input console mode. The following calls lead to SetConsoleMode.

• uv_tty_set_mode calls SetConsoleMode.
• [jl_uv_flush_close_callback] (

  julia/src/jl_uv.c

  Line 228 in 912460b

  uv_tty_set_mode((uv_tty_t*)stream, UV_TTY_MODE_NORMAL);

  ) calls uv_tty_set_mode
• init_stdio_handle calls uv_tty_set_mode
• jl_tty_set_mode calls uv_tty_set_mode

Yeah, that's why I put this in refresh_line so it would get reapplied but maybe the order of things don't work out.
