  [lit] Add LIT_CURRENT_TESTCASE environment variable when running tests (#168762)

I'm not aware of any way for `%run` wrapper scripts like
`iosssim_run.py`
([ref](https://github.com/llvm/llvm-project/blob/d2c7c6064259320def7a74e111079725958697d4/compiler-rt/test/sanitizer_common/ios_commands/iossim_run.py#L4))
to know what testcase they are currently running. This can be useful if
these wrappers need to create a (potentially remote) temporary directory
for each test case.

This adds the `LIT_CURRENT_TESTCASE` environment variable to both the
internal shell and the external shell, containing the full name of the
current test being run.
