Fix --disable-pch build: explicitly delete move constructor

Fix --disable-pch build: explicitly delete move constructor

Without this, the implicitly created constructor is exported by MSVC
for the DLLPUBLIC class, and requires that VirtualDevice is defined,
resulting in this error in PCH-disabled builds:
