Add support in
check-license for conjunctive (AND) licenses. (WordP…
…ress#46801) * Add support in `check-license` for conjunctive (AND) licenses. Conjuctive licenses were being ignored in both the `package.json` and within various LICENSE files. In the first case, this could lead to false negatives $(e.g., 'MIT AND BSD' being treated as non-compatible). In the second case, the implementation was such that only one license was returned (whichever detected license occurred later in `licenseFileStrings`). Based on the ordering of that list, this was likely to cause a false positive, because the non-compatible 'Apache-2.0' license occurs before any of the compatible licenses. Progress on WordPress#38461. * Add unit tests for checkAllCompatible * Update CHANGELOG * Tidy up docblock.
