Zero the workgroup memory for all backends.
We can probably disable this for the backends that support workgroup zeroing, but that's an optimization we can perform later.

When moving private and workgroup variables into the entry point,
generate pointers to pass as arguments to sub-functions on demand,
instead of upfront. This removes a bunch of unnecessary dereferences
for accesses inside the entry point, and one function variable.

Add a transform that pushes these into the entry point and then passes
them by pointer to any functions that need them.
Since WGSL does not allow non-function storage class at
function-scope, add a DisableValidation attribute to bypass this
check.
