fix: doc_links link type - Determine link type at start (fixes#12601)
fixes#12601
Looked like autolink/inline mismatch happened because end_link_type was parsed from the Text/Code events.
I changed it to be determined from the Start event, which should hopefully remain accurate while staying true to the cases where link type may need to be changed, according to the comment
```
// normally link's type is determined by the type of link tag in the end event,
// however in some cases we want to change the link type, for example,
// `Shortcut` type doesn't make sense for url links
```
Hopefully this is the desired behavior?
- remove Valid, it serves no purpose and just obscures the diff
- rename some things
- don't use is_valid_candidate when searching for impl, it's not necessary
fix: Only apply `cfg(test)` for local crates
Don't analyze dependencies with `test`; this should fix various cases where crates use `cfg(not(test))` and so we didn't find things.
"Local" here currently means anything that's not from the registry, so anything inside the workspace, but also path dependencies. So this isn't perfect, and users might still need to use `rust-analyzer.cargo.unsetTest` for these in some cases.

internal: Lift out IdentContext from CompletionContext
Makes things a bit messy overall, but with this I can start cleaning up the render functions properly now.
