CI: Enforce -Wall and -Werror

Part 2 of: #2766 Followup of https://github.com/ornladios/ADIOS2/pull/2639/files Notes from this PR: Wall -Werror enabled for C++ in all builds but: 1. Accent + XL builds 2. Power8 builds 3. Debian buids 4. Using intel compiler translation units that include `nlohmann_json` Signed-off-by: Vicente Adolfo Bolea Sanchez <vicente.bolea@kitware.com>
