RISC-V: Add support for Zvfbfmin extension
This implements the Zvfbfmin extension, as of version 1.0.
View detailed information in:
<https://github.com/riscv/riscv-isa-manual/blob/main/src/bfloat16.adoc#zvfbfmin---vector-bf16-converts>
Depending on different usage scenarios, the Zvfbfmin extension may
depend on 'V' or 'Zve32f'. This patch only implements dependencies
in scenario of Embedded Processor. In scenario of Application
Processor, it is necessary to explicitly indicate the dependent
'V' extension.
For relevant information in gcc, please refer to:
