For SM6.2 and earlier, Raw buffer Loads and Stores can't handle 64 bit
types. This PR expands Raw Buffer Loads and Stores for 64 bit types
double and int64_t. This Adds to the work done in #139996 and #145047 .
Raw Buffer Loads and Stores allow for 64 bit type vectors of size 3 and
4, and the code is modified to allow for that.
Closes#144747
