Use target-level compile definitions for Windows VST3 module

Replace wrapper file approach with target-level compile definitions.
This adds the necessary Windows macros (NOMINMAX, WIN32_LEAN_AND_MEAN,
_UNICODE, _CRT_SECURE_NO_WARNINGS, etc.) to the pluginval target when
building on Windows with VST3 validator enabled.
