1.Is the P3 to XYZ LUT a constant LUT(or constant values)?

Not sure exactly what you are asking, but.. The P3 to XYZ transform is typically done as a colour matrix and gamma adjustment, which could also be baked into a 3D LUT

There is a description of the spi-vfx config's xyz16 space in the docs:

..and the configuration itself:

2.if we make a P3 to XYZ LUT.Do we need the calculated informations of the projector?

No. The P3 to XYZ transform is independent of your projection calibration.

In other words, the P3 to XYZ should be a standard colour transform, which could be used on any calibrated projector.
