1. risc-v/toolchain: configurable vendor ISA extensions

This option allows the platform to enable some vendor-customized ISA extensions,
E.g OpenHW, SiFive, T-Head.

SiFive Intelligence Extensions:
    SiFive Vector Coprocessor Interface(VCIX): xsfvcp
    SiFive FP32-to-int8 Ranged Clip Instructions: Xsfvfnrclipxfqf
    SiFive Matrix Multiply Accumulate Instructions: Xsfvfwmaccqqq
    SiFive Int8 Matrix Multiplication Instructions: XSFvqmaccqoq
Command Line:
    xsfvcp0p1_xsfvfnrclipxfqf0p1_xsfvfwmaccqqq0p1_xsfvqmaccqoq0p1

2. "V" Standard Extension for Vector Operations
3. "Q" Standard Extension for Quad-Precision Floating-Point
