feat(Menu): Option to have it the same width as the trigger

### Feature Description

A possibility to have the https://material.angular.io/cdk/menu/overview take over the width of the container that triggers it.
As an example the grey area should span the full width of the red in the following example:

Currently it seems that you have to provide a fixed width in px. Otherwise it does not work. But you don't always know the exact with of the 'trigger'.

There's an example here: https://vbqdncww.stackblitz.io

In [issue 26336](https://github.com/angular/components/issues/26336) it seems that they are overriding MAT_SELECT_CONFIG to set a `min-width: min-content;`, but have not gotten that to work yet.

### Use Case

It would enable a more consistent styling.

Comienza con la descripción general del menú de Angular CDK y el ejemplo de StackBlitz para reproducir el comportamiento actual del tamaño; issue 26336 proporciona contexto relacionado sobre la configuración del ancho del menú. Se considera completado cuando el menú puede adoptar el ancho del contenedor del trigger sin requerir un ancho fijo en píxeles, con el comportamiento demostrado en un ejemplo o prueba apropiados.
