Group arrays/structs together in the variable pane while debugging.
SkVMSlotInfo now contains a "group index" field in each slot. The
group index starts at zero for the first slot of a variable and
increases by 1 for each slot associated with that variable.
For simple types, this group index will always match the component
index. (This is by far the common case, so the groupIndex field is
omitted from the JSON if the indices match.) For more complicated
types--structs, arrays, or nested combinations thereof--it gives us
a simple way to find the start and end slot of a variable. For a given
slot, we can identify the associated variable's initial slot by
subtracting its group index, and we can identify the last slot of any
variable by walking forward and looking for a group index of zero
(indicating the start of a new, different variable).
