Add optional tool_path_origin to Tools in C++ crosstool

This change adds an optional field to the C++ crosstool proto that
allows configuring the origin tool_path is relative to.

For now, the origin can be one of the following:
  - CROSSTOOL_PACKAGE: If tool_path is a relative path, it's assumed to
    be relative to the package of the crosstool top.
  - FILESYSTEM_ROOT: tool_path is an absolute path. This is checked by
    Bazel.
  - WORKSPACE_ROOT: tool_path must be a relative path and is assumed to
    be relative to the exec-root of the workspace (similar to other
    executables).

Updates bazelbuild/bazel#8438

Closes #10967.
