Avoid generating degenerate dimensions during gather expansions

This gets rid of two cases that used to introduce degenerate dimensions
(dimensions with bound = 1) into the while loop state:

 - Previously we'd explicitly reshape gathers using scalar indices to have a
   minor degenerate dimension.  With this CL we no longer do that - instead we
   push this into the code that looks up the index vector from the gather
   indices tensor.

   dynamic-update-slice-ing into) contain all of the degenerate window dims that
   the gather op would later elide (after the while loop).  With this CL we

Replacing the current inner Cholesky decomposition loop with a While loop rolled version.

This will allow for much larger Cholesky decompositions (and thus matrix inversions) than previously possible on TPU because of the use of rolled While loops so XLA compilation will no longer timeout.

While there is a minor runtime performance decrease (now 25ms vs 15ms for a 500x500 matrix) the compilation time is significantly faster (12.8s vs 55.2s for a 500x500 matrix.)
