Log Message:
CI: disable MSBuild node reuse in the Windows jobs

windows-x86 [syncscumm] fails intermittently on the vert runner with
"MSB4166: Child node N exited prematurely", always in the same phase: the
moment vcpkg's MSBuild integration fans its inline Roslyn task compiles
across the solution's ~9 projects.  The same commit went fail, fail, pass
on three runs.  One trace inlined the dead node's dump -- a
MissingMethodException on System.Runtime.CompilerServices.Unsafe thrown
out of ToolsetConfigurationReader, i.e. the node crashed reading its own
MSBuild.exe.config before binding redirects applied.

MSBuild keeps worker nodes alive for 15 minutes after a build and hands
them back out on a handshake that covers the MSBuild version but not the
environment they were started in.  The runner is a shell executor running
several Windows jobs concurrently under one account -- every failure
overlapped both [syncterm-msvc] and [syncrpg] -- so a build can recruit a
node another job left behind and inherit its toolset environment.

Set MSBUILDDISABLENODEREUSE=1 on every Windows job that drives MSBuild,
through a new .windows-msbuild template.  Reuse only saves node startup on
back-to-back builds; developer builds keep it.

The door jobs this surfaced in were added in 1edeb70972.
