Subject: Disable bazel whole-archive build

V8's bazel configuration system adds the alwayslink parameter (equivalent
to --Wl,-whole-archive on Linux) to all V8 libraries, causing all V8
object files to be included even if they are not referenced. This is more
aggressive than what's done in the GN build system and not needed for
workerd - disabling alwayslink improves the binary size by ~ 1MB as it
allows the linker to eliminate unused symbols.
