Begin Bazel 8 / rules_java 8 compatibility updates

Moves functions out of `//scala:scala.bzl` and updates `WORKSPACE` to
load `//scala:toolchains.bzl` to avoid importing macros that depend on
`JavaInfo` and `java_common` during `WORKSPACE` evaluation. Based on
advice from @hvadehra in bazel-contrib#1652.

Also bumps `.bazelversion` to 7.4.1 in order to upgrade `abseil-cpp` to
20240722.0 and `protobuf` to v29.0. This is instead of keeping
`.bazelversion` at 6.5.0 and setting C++ compiler flags in `.bazelrc` as
described in bazel-contrib#1647.

I haven't tried this under Bzlmod yet, and it still fails with the
following error. Bumping to ScalaPB 1.0.0-alpha.1 in the next commit
fixes this.
