Subject: [PATCH] fix(@angular-devkit/build-angular): reduce fast sourcemap
 threshold

High fidelity sourcemap processing can be expensive for larger bundle sizes.  This reduces the threshold to the original 500KB value to improve performance.

(cherry picked from commit d2dce463d0c7b1cb72e8acd8a0d23a318facfa90)
