split out compile-time known information for master elements

[rcknaus]

Splits out compile-time known information out of the master element, so you can use the isoparametric information directly in gpu kernels if you want.

This was done before in a different and I had a good experience with it. Having the compile-time known information available at compile time simplifies a lot of the data wrangling with the master elements and speeds up the code, at the expense of making the master element-style computations a little more cumbersome.

Implemented for volume-rank SCS and SCV master elements but not face-rank ones. I just want volume for the GCL, so that's the origin of that. I can finish up the face stuff in a bit or as part of this if it's wanted.

Nice work! I like the idea of doing them all in one go and keeping things consistent if that's not too much to ask.
