VS: Update v142 CL flag table for VS 16.10

Run the command

    python3 Source/cmConvertMSBuildXMLToJSON.py -t v142 \
        'c:/.../MSBuild/Microsoft/VC/v160/1033/cl.xml'

To generate `v142_CL.json` locally.  Manually move new and updated
settings over to `Templates/MSBuild/FlagTables/v142_CL.json`.

Revise the `/sourceDependencies[:directives]` table entries to properly
distinguish the two options (because one is a prefix of the other), and
to populate both `Generate*Dependencies` and `*DependenciesFile`.
