Fix jsdoc type resolution

[sandersn]

1. Type resolution did not check for all special assignment kinds. Now it does.
2. Type parameter resolution in @param tags previously used the default walk up the syntax tree, which is incorrect. Type parameters are bound by the containing function, so the walk should start from the parameter itself, not the @param tag.

Notes

1. This branch is based on jsdoc/callback because it relies on the already-improved jsdoc type resolution there.
2. Note that in getJSSpecialAssignment, the predicate for prototype methods is a subset of the predicate in getHostSignatureFromJSDoc, so the prototype method check needs to come first in order to correctly look up types on the source constructor function.

An example of prototype method type resolution is something like this:

/** @template T */
function Z() {
}
/** @param {T} t */
function Z.prototype.M = function(t) { }

Fixes #22621

Edit: Now also fixes #20832
