Switch stdout, stderr to single open in b-mode to solve `Bad file descriptor` exception in callable alias

4

### Motivation In #5631 we found that during execution of callable alias we have [double open](https://github.com/xonsh/xonsh/issues/5631#issuecomment-2252347565) of stdout and stderr descriptors and this produces the [exceptions](https://github.com/xonsh/xonsh/issues/5631#issue-2429860610) in core code or...

### Motivation Windows has slow IO operation on is_file check. So this PR is to reduce running is_file two times. ## For community ⬇️ **Please click the 👍 reaction instead...

Callable alias can provoke `Bad file descriptor` exception in the internal or external code

21

### How it looks for a user The exceptions below are not the root of the issue. It's just consequences of closing the descriptor somewhere in upstream or in parallel...

Two ways for reproduce: ```xsh $XONSH_SHOW_TRACEBACK = True @aliases.register def _e(): echo -n O echo -n E 1>2 execx("echo -n O") execx("echo -n E 1>2") print("o") print("O", file=o) print("E", file=e)...

This is working as expected: ```xsh $XONSH_SHOW_TRACEBACK = True @aliases.register def _e(a,i,o,e): print('O', file=o) print('E', file=e) !(e 1>2) # redirect stdout to stderr # output='', # errors='O\nE\n' ``` But: ```xsh...

Compile xsh xontribs

Hi! xonsh is a giant snail in small conch! I found that xonsh compiles scripts and save it to the `~/.local/share/xonsh/xonsh_script_cache` directory. But xonsh does not compile `.xsh` xontribs unlike...
