Purpose of this PR
Backports #616 behavior from master and 9.x.x, where the vertex attributes from every master node are always generated. It's a performance hit, but one that we can optimize later.
Fixes case 1250275
Testing status
Manual Tests
Created new shaders using every HDRP master node. Connected a vector property to the Vertex Normal and Vertex Tangent slot. Confirmed that when saving, the error no longer reproduces. Generated a shader and confirmed that the attributes struct are generate the needed properties.
Automated Tests
No tests in this PR, but I've made a note in our Favro board to add tests later. We can add tests now, but I didn't want the tests to block the merge as this is an urgent shipstopper for the next package release.
