Revert "[bazel] Add hide symbols from release / fast builds"

This reverts commit 6e4dea75e8.

Reason for revert: This is blocking HEAD import in Copybara.
Let's test this there first, then backport the change.

Original change's description:
> [bazel] Add hide symbols from release / fast builds
>
>
> Our gn build files hide non-exported symbols by default, which results
> in smaller binaries and can improve build times.
>
> This was not ported to the bazel build and causes binary size
> regressions in google 3.
