Subject: [PATCH] fix(@angular-devkit/build-angular): limit advanced terser
 passes to two

Limiting the terser passes to two helps to workaround an issue with terser wherein terser will errantly inline a function argument containing a `yield` expression inside an inner arrow function.  This results in a syntax error since the yield expression is no longer within the scope of a generator.
