Preserve comments for extracted block expression in 'extract_function'
Fix#14371
Preserve comments for extracted block expression in 'extract_function'.
In the original implementation, `block.statements()` was used to construct a new function, removing the comments within the block. In the updated implementation, we use manual traversal of nodes and `hacky_block_expr` to generate a new block, thereby preserving the comments.
Resolve panic in `generate_delegate_methods`
Fixes#16276
This PR addresses two issues:
1. When using `PathTransform`, it searches for the node corresponding to the `path` in the `source_scope` during `make::fn_`. Therefore, we need to perform the transform before `make::fn_` (similar to the problem in issue #15804). Otherwise, even though the tokens are the same, their offsets (i.e., `span`) differ, resulting in the error "Can't find CONST_ARG@xxx."
2. As mentioned in the first point, `PathTransform` searches for the node corresponding to the `path` in the `source_scope`. Thus, when transforming paths, we should update nodes from right to left (i.e., use **reverse of preorder** (right -> left -> root) instead of **postorder** (left -> right -> root)). Reasons are as follows:
In the red-green tree (rowan), we do not store absolute ranges but instead store the length of each node and dynamically calculate offsets (spans). Therefore, when modifying the left-side node (such as nodes are inserted or deleted), it causes all right-side nodes' spans to change. This, in turn, leads to PathTransform being unable to find nodes with the same paths (due to different spans), resulting in errors.
fix: Fix `ast::Path::segments` implementation
calling `ast::Path::segments` on a qualifier currently returns all the segments of the top path instead of just the segments of the qualifier.
The issue can be summarized by the simple failing test below:
```rust
#[test]
fn path_segments() {
//use ra_ap_syntax::ast;
let path: ast::Path = ...; // e.g. `ast::Path` for "foo::bar::item".
let path_segments: Vec<_> = path.segments().collect();
let qualifier_segments: Vec<_> = path.qualifier().unwrap().segments().collect();
assert_eq!(path_segments.len(), qualifier_segments.len() + 1); // Fails because `LHS = RHS`.
}
```
This PR:
- Fixes the implementation of `ast::Path::segments`
- Fixes `ast::Path::segments` callers that either implicitly relied on behavior of previous implementation or exhibited other "wrong" behavior directly related to the result of `ast::Path::segments` (all callers have been reviewed, only one required modification)
- Removes unnecessary (and now unused) `ast::Path::segments` alternatives

fix: Differentiate between vfs config load and file changed events
Kind of fixes https://github.com/rust-lang/rust-analyzer/issues/14730 in a pretty bad way. We need to rethink the vfs-notify layer entirely. For a decent fix.
internal: VFS no longer stores all source files in memory
Turns out there is no need to keep the files around. We either upload them to salsa once processed, or we need to keep them around for the `DidChangeTextDocumentNotification`, but that notification is only valid for opened documents, so instead we can just keep the files around in the `MemDocs`!
Fixes https://github.com/rust-lang/rust-analyzer/issues/16301
