This implements the Zvfbfwma extension, as of version 1.0. View detailed information in: <https://github.com/riscv/riscv-isa-manual/blob/main/src/bfloat16.adoc#zvfbfwma---vector-bf16-widening-mul-add> 1 In spec: "Zvfbfwma requires the Zvfbfmin extension and the Zfbfmin extension." 1.1 In Embedded Processor: Zvfbfwma -> Zvfbfmin -> Zve32f 1.2 In Application Processor: Zvfbfwma -> Zvfbfmin -> V 1.3 In both scenarios, there are: Zvfbfwma -> Zfbfmin 2 Depending on different usage scenarios, the Zvfbfwma extension may depend on 'V' or 'Zve32f'. This patch only implements dependencies in scenario of Embedded Processor. This is consistent with the processing strategy in Zvfbfmin. In scenario of Application Processor, it is necessary to explicitly indicate the dependent 'V' extension.
