JS: fix bounds checking (Issue 23123)
* For ByteArray-based bounds-checking, the JavaScript backend must use the
`len` field, instead of the inbuild JavaScript `length` field.
* Range-based operations must also check both the start and end of the range
for bounds
* All indicies are valid for ranges of size zero, since they are essentially no-ops
* For cases of ByteArray accesses (e.g. read as Int), the end index is
(i * sizeof(type) + sizeof(type) - 1), while the previous implementation
uses (i + sizeof(type) - 1). In the Int32 example, this is (i * 4 + 3)
* IndexByteArrayOp_Word8As* primitives use byte array indicies (unlike
the previous point), but now check both start and end indicies
* Byte array copies now check if the arrays are the same by identity and
then if the ranges overlap.

Fix remaining issues with bound checking (#23123)
While fixing these I've also changed the way we store addresses into
ByteArray#. Addr# are composed of two parts: a JavaScript array and an
offset (32-bit number).
Suppose we want to store an Addr# in a ByteArray# foo at offset i.
Before this patch, we were storing both fields as a tuple in the "arr"
array field:
foo.arr[i] = [addr_arr, addr_offset];
Now we only store the array part in the "arr" field and the offset
directly in the array:
foo.dv.setInt32(i, addr_offset):
foo.arr[i] = addr_arr;
It avoids wasting space for the tuple.

Improved documentation for the Data.OldList.nub function
There was recomentation to use map head . group . sort instead of nub
function, but containers library has more suitable and efficient
analogue
