Joseph Doherty 80104caf09 sidecar: switch Wonderware historian sidecar from x86 to x64 ...

The sidecar was set to PlatformTarget=x86 + Prefer32Bit=true to mirror
v1's Driver.Galaxy.Host bitness, which itself was x86 only because of
MXAccess COM. PR 7.2 retired Galaxy.Host, so that constraint is gone.

AVEVA Historian 2020 ships an x64 build of every SDK assembly the
sidecar needs (lib\aahClientManaged.dll + aahClient.dll + aahClientCommon.dll
sourced from C:\Program Files (x86)\Wonderware\Historian\x64\; the
remaining three SDK assemblies — Historian.CBE / DPAPI /
ArchestrA.CloudHistorian.Contract — are pure-managed AnyCPU and load
in either bitness). Drop PlatformTarget to x64 on both the sidecar
project and its test project; running 37/37 historian tests + the
live install confirms the SDK loads and serves the named pipe in a
64-bit-native process.
