Draft Extension: Zfb

Feature Description

This branch implemented Zfb draft extension from zfb branch of riscv-isa-manual.

Since newer draft of Zfb extension requires additional instructions with complex handling and the extension name itself is renamed to Zfa, this branch itself is deprecated.

However, it can be a good example to add instructions to the GNU toolchain. So, this branch is kept for educational purposes (until Zfa is ratified and upstreamed).
