Run debuginfo tests against rust-enabled lldb, when possible

If the rust-enabled lldb was built, then use it when running the
debuginfo tests.  Updating the lldb submodule was necessary as this
needed a way to differentiate the rust-enabled lldb, so I added a line
to the --version output.

This adds compiletest commands to differentiate between the
rust-enabled and non-rust-enabled lldb, as is already done for gdb.  A
new "rust-lldb" header directive is also added, but not used in this
patch; I plan to use it in #54004.

This updates all the tests.
