Add `transform::DecomposeStridedMatrix`, which replaces matrix members of storage or uniform buffer structures, that have a [[stride]] decoration, into an array
of N column vectors.
This is required to correctly handle `mat2x2` matrices in UBOs, as std140 rules will expect a default stride of 16 bytes, when in WGSL the default structure layout expects a stride of 8 bytes.

As all loops in the parser require `synchronized_` to be true, don't set this to true if we've hit the maximum number of error diagnostics.
This lets the parser bubble up as soon as the limit was reached, instead of only aborting once we finally reach the top level loop.
ClusterFuzz has uncovered a number of cases where, in a loop, it can produce an error, then resynchronize, then error again on the next loop iteration. This produces more than the max limit of errors, and can stall the tests long enough to time out.
No unit tests for this, as it requires a really contrived input to trigger, and to exhaustively catch all the places we now call maybe_set_synchronized() would result in a large colleciton of horrible tests. Instead, let ClusterFuzz do the testing.
