[es2015] Change JSArrayBufferView::byte_length/byte_offset to uintptr_t. This is the next step to support large array buffers. On 64-bit archs the full safe integer range is available (up to 2^53-1 bytes in theory). On 32-bit platforms the full Unsigned31 range is allowed, so that we can continue to use CheckBounds for typed arrays and data views in the optimizing compiler (it's generally unlikely that the kernel will give you more than 1GiB of contiguous memory anyways). Drive-by-fix: This introduces proper chokepoints for the byte_offset and byte_length accesses in the CSA code, and also does some renaming for consistency.
