Sean Huang 6ae8b8aa7c Upgrade V8 to 152.2.0 and backport Array.sort safety guards (#54519) ...

## Why

Optimized `Array.prototype.sort` can write objects into incompatible array element storage when receiver element kinds differ and the comparator mutates the array.

## What changed

- Upgrade `v8` to `152.2.0`, the Bazel V8 source to `15.2.124.1`, and ICU data and initialization to version 78.
- Backport element-kind agreement checks for sort inlining in TurboFan and Maglev. Apply the patch to Bazel builds and Windows MSVC source builds, and include it in source-build cache keys and canary triggers.
- Refresh pinned sandbox archives and bindings, extend Bazel prebuilt coverage to musl Linux, and use matching sandbox bindings on Windows MSVC.
- Update Bazel integration patches and runtime dependencies for the new V8 release, and download the pinned Windows build tools in source-build workflows.

## Testing

Include the upstream sort regression test covering mixed element kinds, comparator mutation, and continued optimization for matching kinds. Add a test requiring canary and Windows source builds when the backport changes, and update artifact-fetch tests for the new version.
