e700a6a764 Add ityp::vector class and unittests
In order to remove the kMaxBindingsPerGroup limit in Dawn, some static
ityp::arrays need to be made dynamically sized. This CL adds ityp::vector
wrapping std::vector.

This CL also fixes the assumption that ityp::stack_vec iterators are pointers

d761d5a575 Add Chromium's StackVector base class and ityp::stack_vec
In order to lift Dawn's restriction on the number of bindings
per bind group, static sized arays need to be converted to
dynamically sized vectors. This CL adds Chromium's StackVector
class which behaves like std::vector but provides a stack allocator
to allocate small vectors on the stack. Dawn can use this to avoid
making separate heap allocations for a smaller, realistic binding
counts.

The CL also adds an ityp::stack_vec class to support using
a StackVector with TypedInteger indices.
