Fixes #102300 without L1 packing
This PR changes the SH coefficients used for encoding direct light sources. This requires that the L1 packing method also should be adjusted since it is tightly coupled to the SH coefficients. This PR does this by disabling L1 packing all together effectively undoing #96114.
