fix: use clamped coordinate in TextureViewImpl::_getTexelPtr (#752)

The _getTexelPtr function computes a clamped coordinate value 'coord' but
then uses the original unclamped 'texelCoords[axis]' for the offset
calculation. This means the bounds clamping logic is completely
ineffective, allowing out-of-range texel coordinates to read or write
arbitrary memory relative to the texture data buffer.

Fix by using the clamped 'coord' variable instead of 'texelCoords[axis]'
in the offset calculation, matching the pattern used in SampleLevel().
