Skia is working on making `SkPath` immutable:
https://skia-review.googlesource.com/c/skia/+/1075478

In Flutter Web's CanvasKit renderer, we use `SkPath` as a mutable
object, which made the [Skia
roll](#177184) fail. To fix this,
we should start using `SkPathBuilder` instead.

Remaining work:
- [x] Figure out the deletion/disposal of `SkPath`s generated from
`.snapshot()` calls.
- [ ] `LazyPath` should be restructured to better accommodate a world of
immutable paths and path builders (coming in a future PR).

I bumped templates to the correct versions. I also included a fix for
kgp and agp compatability.

AGP 8.11.0 -> 8.11.1
Gradle 8.13 -> 8.14
KGP 2.2.0 -> 2.2.20

I ran `flutter analyze --suggestions` and `flutter build apk` to ensure
these are safe versions.

Will cherry pick this to beta after the pr merges.

Fixes #177320
