Allow NVIDIA Blackwell (#6991)
NVIDIA Blackwell GPU generation has number 10. The SM code and
architecture should be `100`, but the current code generates `1.`,
because it expects a 2 characters string.
This change modifies the logic to consider it as a string that contains
a `.`, hence splits the string and uses the array of strings.
