Converts the bfloat16_t type to the fp4x2_e1m2_t type, and supports multiple rounding modes.
- RINT rounding mode: round half to even
- ROUND rounding mode: round half up
- FLOOR rounding mode: round toward negative infinity
- CEIL rounding mode: round toward positive infinity
- TRUNC rounding mode: round toward zero
Since the bit-width ratio of the source operand type to the destination operand type is 4:1, when writing data, the data of one VL size needs to be divided into four parts, and index 0, index 1, index 2, or index 3 is selected according to different interfaces.
