Use `Runtime#availableProcessors` on Linux

As of JDK 11, `Runtime#availableProcessors` on Linux is aware of cgroup resource limits and thus behaves as expected in containers, whereas `/proc/cpuinfo` still reports the number of logical processors available to the host.

Unfortunately, the JVM-internal `os::total_memory` function, which similarly takes cgroup limits into account when computing the available RAM, does not seem to be accessible from Java.

Fixes #5042

Closes #16512.

RELNOTES[INC]: Bazel's local CPU resource on Linux is now container aware. Use `--local_cpu_resources`, `--loading_phase_threads` or `--jobs` to override.
