Resolve inlay hint data
Part of https://github.com/rust-lang/rust-analyzer/issues/13962
Support https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#inlayHint_resolve better, by omitting all inlay hint fields specified in the client hint resolve capabilities.
Current list of all capabilities possible to resolve later:
```
"textEdits"
"tooltip"
"label.tooltip"
"label.location"
"label.command"
```
and every one specified in the client capabilities is now resolved by r-a, being omitted in the initial response.

When editing `inlay_hints.rs` file around line `457` with no resolve capabilities, I get

with all unresolved parts needing only for navigation, hover or applying the hint edit — dynamic parts that are made after mouse hover or similar events, that resolve the hint data.
Do not send inlay hint refresh requests on file edits
See https://github.com/rust-lang/rust-analyzer/issues/13369#issuecomment-1695306870
Editor itself is able to invalidate hints after edits, and /refresh was sent after editor reports changes to the language server. This forces the editor to either query & invalidate the hints twice after every edit, or wait for /refresh to come before querying the hints.
Both options are rather useless, so instead, send a request on server startup only: client editors do not know when the server actually starts up, this will help to query the initial hints after editor was open and the server was still starting up.
On type format '(', by adding closing ')' automatically
If I understand right, `()` can surround pretty much the same `{}` can, so add another on type formatting pair for convenience: sometimes it's not that pleasant to write parenthesis in `Some(2).map(|i| (i, i+1))` cases and I would prefer r-a to do that for me.
One note: currently, b06503b6ec/crates/rust-analyzer/src/handlers/request.rs (L357) fires always.
Should we remove the assertion entirely now, since apparently things work in release despite that check?

Previously this was hard coded to "0.1". The SCIP protocol allows this
to be an arbitrary string:
```
message ToolInfo {
// Name of the indexer that produced this index.
string name = 1;
// Version of the indexer that produced this index.
string version = 2;
// Command-line arguments that were used to invoke this indexer.
repeated string arguments = 3;
}
```
so use the same string reported by `rust-analyzer --version`.
SCIP requires symbols to be unique, but multiple functions may have a
parameter with the same name. Qualify parameters according to the
containing function.
internal: Defer structured snippet rendering to allow escaping snippet bits
Since we know exactly where snippets are, we can transparently escape snippet bits to the exact text edits that need it, and not have to do it for anything other text edits.
Also will eventually fix#11006 once all assists are migrated. This comes as a side-effect of text edits that don't have snippets get marked as having no insert formatting at all.
Structured snippets precisely track which text edits need to be marked
as snippet text edits, but the cases where structured snippets aren't
used but snippets are still present are for simple single text-edit
changes, so it's perfectly fine to mark all one of them as being a
snippet text edit
