[stdlib] Patch bool dtypepointer load

[bgreni]

This PR offers a temporary fix to address #2813 in case the team cannot currently prioritize this, and I imagine a proper fix requires changes at a deeper level than OS contributors have access to?

Thanks for patching this

I suppose there's a chance that the original behavior of packing the bits is desired? but I'm not sure.. at the very least it's inconsistent with itself.
it definitely confused me when i first saw it, but pointers are not meant to be safe. If it is desired, maybe have a separate method to allow packing and unpacking in a way that's consistent with it's offset

I think that fact that my change works could point to .bitcast[SIMD[DType.bool, width]]().load() not working as intended? Regardless I think this code should work as expected and any special logic required to make it work should be implemented internally. Seems like a pretty major footgun that has no need to exist in a brand new language.
