Add configurable size limit for persistent build cache with LRU eviction

### Command

build, serve

### Description

The Angular CLI persistent disk cache (`.angular/cache`) grows without bounds. On large projects, a single checkout accumulates tens of gigabytes of cached build artifacts. In our case, a single checkout reached **29 GB**.

This was previously raised in #25116 and closed as not feasible with Webpack. Since Angular 17+, the build system uses esbuild, so the original constraint no longer applies.

### Describe the solution you'd like

Add a configurable size cap (e.g., `cli.cache.maxSize`) with LRU eviction when the limit is reached. This is a common pattern in build tooling — Turborepo, Gradle, and most browsers' HTTP caches all implement bounded persistent caches.

Example configuration:
```json
"cli": {
"cache": {
"enabled": true,
"maxSize": "2GB"
}
}
```

When the cache exceeds `maxSize`, the oldest/least-recently-used entries are evicted.

### Describe alternatives you've considered

- Periodically running `ng cache clean` or manually deleting `.angular/cache` — works but is a manual maintenance burden, especially for developers unaware the cache is growing.

Comienza con la caché persistente utilizada por los comandos `build` y `serve`, y compárala con el punto de entrada existente `ng cache clean` para `.angular/cache`. Define cómo se configura y se mide `cli.cache.maxSize` y, a continuación, verifica que las entradas menos recientemente utilizadas se desalojen una vez superado el límite configurado.
