JSDoc type aliases aren't parsed or bound at the end of blocks

Bug Report

Followup to #54037 and #53624
This is not a regression, and fixing it would require

• the parser to check for jsdoc before each close brace
• the ast to store optional jsdoc on each close brace, and store the close brace on each block
• the binder to visit each close brace to check for jsdoc to bind

So I think it's too expensive for a feature that nobody has noticed missing until recently.

🕗 Version & Regression Information

• This is the behavior in every version I tried

💻 Code

// @filename: typedefAtEndOfBlock.js
// @checkJs: true
// @outdir: dist
// @declaration: true
function f() {
  /* @type {A} */
  var a = 2
  /** @typedef {string} A */
}
{
  /* @type {B} */
  var b = 2
  /** @typedef {string} B */
}
export class Class {
  /* @type {C} */
  c = 1
  /** @typedef {string} C */
}
const Dlass = class {
  /* @type {D} */
  d = 1
  /** @typedef {string} D */
}

🙁 Actual behavior

None of the typedefs are parsed or bound.

🙂 Expected behavior

The typedefs are parsed and bound.
(And none are visible outside their containers, which is not true for classes right now).

Comienza con la reproducción en typedefAtEndOfBlock.js y sigue cómo parser, AST y binder gestionan JSDoc antes de las llaves de cierre. Compara el comportamiento descrito en #54037 y #53624. Se considera terminado cuando los typedefs se analizan y se enlazan dentro de sus contenedores, y se aborda el comportamiento documentado de visibilidad de class.
