BUG: Fix GPUPDEDeformable module dependencies

Move ITKPDEDeformableRegistration and ITKGPURegistrationCommon from
COMPILE_DEPENDS to DEPENDS because public headers in this module
include headers from ITKPDEDeformableRegistration (specifically
itkDemonsRegistrationFilter.h). This fixes compilation errors when
building tests that cannot find the required headers.

The error was:
error C1083: Cannot open include file: 'itkDemonsRegistrationFilter.h'

COMPILE_DEPENDS only makes headers available during the compilation
of the module's source files, but not for tests or dependent modules.
Since the public API depends on these headers, they must be listed
as regular DEPENDS.
