avutil/mips: refactor msa SLDI_Bn_0 and SLDI_Bn macros.
Changing details as following:
1. The previous order of parameters are irregular and difficult to
understand. Adjust the order of the parameters according to the
rule: (RTYPE, input registers, input mask/input index/..., output registers).
Most of the existing msa macros follow the rule.
2. Remove the redundant macro SLDI_Bn_0 and use SLDI_Bn instead.
