[llvm] [llvm-lit] Resolve TypeError in built-in cat -v implementation (PR #98363)

[via llvm-commits]

https://github.com/connieyzhu created https://github.com/llvm/llvm-project/pull/98363

When using -v in lit's internal implementation of cat, there is a TypeError when the file data is passed into convertToCaretAndMNotation() as a str, because bytearray() requires an encoded string. This patch encodes the str before passing it through bytearray().
