Charles Lyding f249e7e856 perf(@angular/cli): enable Node.js compile code cache when available

The Angular CLI will now enable the Node.js compile cache when available
for use. Node.js v22.8 and higher currently provide support for this feature.
The compile cache stores the v8 intermediate forms of JavaScript code for the Angular
CLI itself. This provides a speed up to initialization on subsequent uses the Angular CLI.
The Node.js cache is stored in a temporary directory in a globally accessible
location so that all Node.js instances of a compatible version can share the
cache. The code cache can be disabled if preferred via `NODE_DISABLE_COMPILE_CACHE=1`.

Based on initial profiling, this change provides an ~6% production build time
improvement for a newly generated project once the cache is available.

```
Benchmark 1: NODE_DISABLE_COMPILE_CACHE=1 node ./node_modules/.bin/ng build
  Time (mean ± σ):      2.617 s ±  0.016 s    [User: 3.795 s, System: 1.284 s]
  Range (min … max):    2.597 s …  2.640 s    10 runs

Benchmark 2: node ./node_modules/.bin/ng build
  Time (mean ± σ):      2.475 s ±  0.017 s    [User: 3.555 s, System: 1.354 s]
  Range (min … max):    2.454 s …  2.510 s    10 runs

Summary
  node ./node_modules/.bin/ng build ran
    1.06 ± 0.01 times faster than NODE_DISABLE_COMPILE_CACHE=1 node ./node_modules/.bin/ng build
