Make xonsh tolerant to inaccessible paths: history backend, script ca…

…che (#5430)

Closes #5319

### Before

```xsh
mkdir -p /tmp/noaccess
chmod 000 /tmp/noaccess
echo 'print(1)' > /tmp/1.xsh

xonsh --no-rc --no-env -DXONSH_DATA_DIR='/tmp/noaccess'
# Json History error

xonsh --no-rc --no-env -DXONSH_DATA_DIR='/tmp/noaccess' /tmp/1.xsh
# Script cache error
```

### After

```xsh
mkdir -p /tmp/noaccess
chmod 000 /tmp/noaccess
echo 'print(1)' > /tmp/1.xsh

xonsh --no-rc --no-env -DXONSH_DATA_DIR='/tmp/noaccess'
# Error during load <class 'xonsh.history.json.JsonHistory'>: [Errno 13] Permission denied: '/tmp/noaccess/history_json'
# Set $XONSH_HISTORY_BACKEND='dummy' to disable history.
# History disabled.
# @

xonsh --no-rc --no-env -DXONSH_DATA_DIR=/tmp/noaccess /tmp/1.xsh
# xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True
# update_cache: Cache file is not writable: /tmp/noaccess/xonsh_script_cache/private/tmp/1_.xsh.cpython-311
# Set $XONSH_CACHE_SCRIPTS=0, $XONSH_CACHE_EVERYTHING=0 to disable cache.
# 1
```
And no warnings when everything is switched off:
```xsh
xonsh % python -m xonsh --no-rc --no-env -DXONSH_DATA_DIR=/tmp/noaccess -DXONSH_HISTORY_BACKEND=dummy
# @

xonsh --no-rc --no-env -DXONSH_DATA_DIR=/tmp/noaccess -DXONSH_CACHE_SCRIPTS=0 -DXONSH_CACHE_EVERYTHING=0 /tmp/1.xsh
# 1
```
