Subject: [lldb] Add a compiler/interpreter of LLDB data formatter bytecode to
 examples

This PR adds a proof-of-concept for a bytecode designed to ship and
run LLDB data formatters. More motivation and context can be found in
the formatter-bytecode.rst file and on discourse.

https://discourse.llvm.org/t/a-bytecode-for-lldb-data-formatters/82696

Relanding with a fix for a case-sensitive path.
