The lsp location type has the lsp's URI type and a range. We can replace
that with a custom type private to the lsp commands module that uses the
core URI type instead.
We can't entirely replace the type with a new Location type in core.
That type might look like:
pub struct Location {
uri: crate::Uri,
range: crate::Range,
}
But we can't convert every `lsp::Location` to this type because for
definitions, references and diagnostics language servers send documents
which we haven't opened yet, so we don't have the information to convert
an `lsp::Range` (line+col) to a `helix_core::Range` (char indexing).
This cleans up the picker definitions in this file so that they can all
use helpers like `jump_to_location` and `location_to_file_location` for
the picker preview. It also removes the only use of the deprecated
`PathOrId::from_path_buf` function, allowing us to drop the owned
variant of that type in the child commit.
