Build: compile with simd extensions
This MR makes CMakeLists.vtk.txt try to compile libjpeg-turbo with the SIMD extensions.
The goal here is to get a 4x speed up in vtkJPEGWriter for x86_64 and ARM architectures.
We will need to bring NASM as a compilation dependency in VTK's CI for x86_64 targets (ARM targets don't need it).
