Description

gopls' deprecated analyzer reports a diagnostic for each reference to a deprecated package-level symbol or concrete method. (It uses the LSP's hint severity and deprecated tag to make it subtle.) However, it does not report references to deprecated fields, such as the Obj field of ast.Ident, declared thus:

	// An Ident node represents an identifier.
	Ident struct {
		NamePos token.Pos // identifier position
		Name    string    // identifier name
		Obj     *Object   // denoted object, or nil. Deprecated: see Object.
	}

It should support field references too. And interface methods.

Research direction
Examine the deprecated analyzer's source code in x/tools/gopls/internal/analysis/deprecated to understand how it detects deprecated symbols. Then add logic to also detect deprecated fields and interface methods. Look at the AST nodes for field declarations and interface method definitions.
