Oleksii Kurochko 1e6cd4155d xen/riscv: introduce extension support check by compiler ...

Currently, RISC-V requires two extensions: _zbb and _zihintpause.

This patch introduces a compiler check to check if these extensions
are supported.
Additionally, it introduces the riscv/booting.txt file, which contains
information about the extensions that should be supported by the platform.

In the future, a feature will be introduced to check whether an extension
is supported at runtime.
However, this feature requires functionality for parsing device tree
source (DTS), which is not yet available.
