738e9276 - Add executed MC/DC TestVectors to `llvm-cov export` (#159119)

Add executed MC/DC TestVectors to `llvm-cov export` (#159119) It adds a new JSON array with the list of test vectors to the end of the mcdc_records. I also bumped the json format version accordingly, which I believe wasn’t done properly in the past when new fields were added. This PR adds tests and comment docs for https://github.com/llvm/llvm-project/pull/105511 --------- Co-authored-by: Arpad Borsos <swatinem@swatinem.de>
