clangd uses a completely different semantic token legend than SourceKit-LSP (it doesn’t even adhere to the ordering of the pre-defined token types) but we were passing index offsets from clangd through assuming that clangd uses the same legend, which was incorrect. When retrieving semantic tokens from clangd, translate the semantic tokens from clangd’s legend to SourceKit-LSP’s legend. rdar://129895062
