Indent guides can be configured per language, meaning that in a multi
buffer we can get excerpts where indent guides should be
disabled/enabled/styled differently than other excerpts.
Imagine the following scenario, i have indent guides disabled in my
settings, but want to enable them for JS and Python. I also want to use
a different line width for python files. Something like this is now
supported:
<img width="445" alt="image"

And the relevant settings for the example above:
```json
"indent_guides": {
"enabled": false
},
"languages": {
"JavaScript": {
"indent_guides": {
"enabled": true
}
},
"Python": {
"indent_guides": {
"enabled": true,
"line_width": 5
}
}
}
```
Release Notes:
- Respect language specific settings when showing indent guides in a
multibuffer
- Fixes an issue where indent guide specific settings were not
recognized when specified in local settings
