fix(@angular/build): ignore virtual esbuild paths with (disabled):

Virtual files generated by esbuild for disabled browser fields leak into the
watch list, causing spurious rebuilds in watch mode.

Previously, only paths where the suffix was a Node.js builtin module were
ignored. Now, any path containing `(disabled):` is ignored as it represents
a virtual file that doesn't exist on disk.

Fixes #33160
