### Motivation
There is no way to access to the CommandPipeline of executed command in
uncaptured mode. This causes:
* No chance to get return code in one universal way.
* Barrier to trace and inspection.
### Before
```xsh
$(ls nofile)
# No way to access to the CommandPipeline of executed command.
```
### After
```xsh
$(ls nofile)
__xonsh__.last.rtn # In interactive or not interactive.
# 2
```
```xsh
# Sugar sir:
last = type('LastCP', (object,), {'__getattr__':lambda self, name: getattr(__xonsh__.last, name) })()
ls nofile
last.rtn
# 2
```
JFYI #5342

### Motivation
* To have an ability to manage the output format added ``$XONSH_SUBPROC_OUTPUT_FORMAT`` to switch the way to return the output lines. Default ``stream_lines`` to return text. Alternative ``list_lines`` to return the list of lines. Also supported custom lambda function.
* Additionally the [proposal to change default behavior](https://github.com/xonsh/xonsh/pull/5377#discussion_r1587627131) for a single line case.
* Closes#3924 as soft solution.
### Before
```xsh
mkdir -p /tmp/tst && cd /tmp/tst && touch 1 2 3
$(ls)
# '1\n2\n3\n'
id $(whoami)
# id: ‘pc\n’: no such user: Invalid argument
du $(ls)
# du: cannot access '1'$'\n''2'$'\n''3'$'\n': No such file or directory
ls $(fzf)
# ls: cannot access 'FUNDING.yml'$'\n': No such file or directory
```
### After
```xsh
mkdir -p /tmp/tst && cd /tmp/tst && touch 1 2 3
$XONSH_SUBPROC_OUTPUT_FORMAT = 'list_lines'
$(ls)
# ['1', '2', '3']
[f for f in $(ls)]
# ['1', '2', '3']
id $(whoami)
# uid=501(user) gid=20(staff)
du $(ls)
# 0 1
# 0 2
# 0 3
ls $(fzf)
# FUNDING.yml
# etc
mkdir -p /tmp/@($(whoami))/dir
cat /etc/passwd | grep $(whoami)
```
### Notes
* It will be good to improve parser for cases like `mkdir -p /tmp/$(whoami)/dir`. PR is welcome!
* I named the default mode as `stream_lines` (instead of just `stream` or `raw`) because in fact we transform raw output into stream of lines and possibly reduce the length of output ([replacing `\r\n` to `\n`](c3a12b2a9c/xonsh/procs/pipelines.py (L380-L383))). May be some day we need to add raw "stream" output format.
* Now anybody can implement bash `IFS` behavior in [bashisms](https://github.com/xonsh/xontrib-bashisms).
