This patch changes invocations of `spicyz` and similar Spicy tools in tests which perform compilation to use debug mode via passing `-d`. This in turn leads to Spicy compiling generated C++ code in debug as opposed to release mode which typically seems to require less CPU time and RAM. For a local test running with `btest -j 16` and no caching via `HILTI_CXX_COMPILER_LAUNCER` this sped up running of BTests under `spicy/` by about 40s on my machine (120s vs 160s).
