V8 Bazel Build (#15021)
Alternative approach, we use rusty_v8 for all platforms that its
predefined, but lets build from source a musl v8 version with bazel for
x86 and aarch64 only. We would need to release this on github and then
use the release.

# What: replace upstream V8 module dependency bootstrapping with repository
# declarations and dependency setup that match this Bazel workspace.
# Scope: upstream MODULE.bazel only; affects external repo resolution and Bazel
# module wiring, not V8 source files.
