[RISCV][COST] Add half type support for the cost model of sqrt/fabs

[Miss_Grape]

Summary

1. Refactor for costs of sqrt/fabs
2. Add half type support for the cost model of sqrt/fabs

[reames]

Please update the review description to describe actual change. In this case, I think you're adding half support.

ST->hasVInstructionF16() is only true if hasVInstructions() is true so this || doesn't do anything.
