This takes a similar approach as b9b6938183, and shares some code.
The code sharing is limited as inlay hints wants to deduce the type of the
variable rather than the type of the `auto` per-se.
It drops support (in both places) for multiple instantiations yielding the same
type, as this is pretty rare and hard to build a nice API around.

While here, fix an ugliness:
auto foo()->auto { return 42; }
This (silly) code gains a "-> int" hint. While correct and useful, it renders as
auto foo()->int->auto { return 42; }
which is confusing enough to do more harm than good I think.

These make the init lists appear as if designated initialization was used.
Example:
ExpectedHint{"param: ", "arg"}
becomes
ExpectedHint{.Label="param: ", .RangeName="arg"}

The idea is that the feature will always be advertised at the LSP level, but
depending on config we'll return partial or no responses.
We try to avoid doing the analysis for hints we're not going to return.
Examples of syntax:
```
InlayHints:
Enabled: No
---
InlayHints:
ParameterNames: No
---
InlayHints:
ParameterNames: Yes
DeducedTypes: Yes
```

This means it's a "real feature" in clangd 14, albeit one that requires special
client support.
- remove "preview" from the flag description
- expose the `clangdInlayHints` capability by default
- provide `position` as well as `range`
- support `InlayHintsParams.range` to restrict the range retrieved
- inlay hint list is in document order (sorted by position)
Still to come: control feature via config rather than flag.

This implements the following changes:
* AutoType retains sugared deduced-as-type.
* Template argument deduction machinery analyses the sugared type all the way
down. It would previously lose the sugar on first recursion.
* Undeduced AutoType will be properly canonicalized, including the constraint
template arguments.
* Remove the decltype node created from the decltype(auto) deduction.
As a result, we start seeing sugared types in a lot more test cases,
including some which showed very unfriendly `type-parameter-*-*` types.
