LOG: [llvm-lto2] Added version command for llvm-lto2 (#148866)

Previously, the only way to check version for llvm-lto2 was to add
version as a subcommand: `llvm-lto2 run --version`. This adds version as
a main command for llvm-lto2 for more intuitive access.

You can now check version with the command `llvm-lto2 --version`.
