fix(ols): remove single_file_support (#2952)

* fix(ols): remove single_file_support

It doesn't seem like ols really has support for single_file_support. The
ols application crashes with the following message:
"ols/src/server/requests.odin(1494:28) Index 0 is out of range 0..<0\n"

This happens on workspace/didChangeConfiguration when settings are
provided in the users' ols setup.

To work around this, essentially turning off single_file_support
& adding *.odin as a way to detect a root_dir. This isn't very common
but at least one other language server uses this method, qml_ls.
However, without this, the ols doesn't really work out of the box for
projects that lack a .git directory or ols.json file.

* fix(ols): remove single_file_support that defaults to false
