fix(@angular-devkit/build-angular): improve file watching on Windows when using certain IDEs

[alan-agius4]

This commit, fixes a file watching issue where file changes events are not triggered when using IDEs like Visual Studio (not VS Code).

The main changes to solve the issue are;

Replace watcher.on('all') with watcher.on('raw')

Using watcher.on('all') does not capture some of events fired when using Visual studio and this does not happen all the time, but only after a file has been changed 3 or more times.

watcher.on('raw')
Change 1
rename | 'C:/../src/app/app.component.css'
rename | 'C:/../src/app/app.component.css'
change | 'C:/../src/app/app.component.css'

Change 2
rename | 'C:/../src/app/app.component.css'
rename | 'C:/../src/app/app.component.css'
change | 'C:/../src/app/app.component.css'

Change 3
rename | 'C:/../src/app/app.component.css'
rename | 'C:/../src/app/app.component.css'
change | 'C:/../src/app/app.component.css'

watcher.on('all')
Change 1
change | 'C:\\..\\src\\app\\app.component.css'

Change 2
unlink | 'C:\\..\\src\\app\\app.component.css'

Change 3
... (Nothing)

Handle rename events

Some IDEs will fire a rename event instead of unlink/changed when a file is modified}

Closes #26437
