The Server job's Build step dominates the pipeline (~6m37s of a ~9.5m job;
the dictionary/integration test is only ~43s). sccache caches individual
MSVC compiles across runs so an incremental change rebuilds only what it
touched instead of the whole server + engine tree.
sccache only caches an MSVC compile whose debug info is embedded in the
object, so switch the Server build's Release debug info from /Zi to /Z7.
The linker's /DEBUG still emits the beside-the-executable PDB the release
job validates, so the symbol layout is unchanged.
Its compiler-launcher hook is honoured only by the Ninja and Makefile
generators, so configure the Server build with Ninja Multi-Config (keeping
the --config Release / bin/Release layout the later steps depend on) and
add an MSVC-environment step, since Ninja does not locate cl.exe on its own.
