Fix a bug in computing bind group index in GroupsInheritUpTo()

This patch fixes a crash issue on D3D12 backends that are caused by
a bug in computing bind group index in function GroupsInheritUpTo().
The return value of this function should be kMaxBindGroups instead of
(kMaxBindGroups + 1) as the maximum number of bind group sets is
kMaxBindGroups.

This patch also adds a regression test on this bug.
