Muir Manders 49ba83114e internal/lsp: improve composite literal completion
When the value of a composite literal key/value pair was unparsable,
you were getting completions for the composite literal keys instead of
values. For example "struct { foo int }{foo: []<>" was completing to
the field name "foo". This was because the leaf ast.Node at the cursor
was the composite literal itself, and our go-back-one-character logic
was not happening because the preceding character's node
was *ast.BadExpr, not *ast.Ident. Fix by always generating the ast
path for the character before the cursor's position. I couldn't find
any cases where this broke completion.

I also added expected type detection for the following composite
literal cases:
- array/slice literals
- struct literals (both implicit and explicit field names)
- map keys and values

Fixes golang/go#29153
