Charles Zablit 7345233fb6 [lldb] improve the heuristics for checking if a terminal supports Unicode (#171832) ...

This patch improves the way lldb checks if the terminal it's opened in
(if any) supports Unicode or not.

On POSIX systems, we check if `LANG` contains `UTF-8`.

On Windows, we always return `true` since we use the `WriteToConsoleW`
api.

This is a relanding of https://github.com/llvm/llvm-project/pull/168603.

The tests failed because the bots support Unicode but the tests expect
ASCII. To avoid different outputs depending on the environment the tests
are running in, this patch always force ASCII in the tests.
