Note 1

Due to a warning (treated as error) related to RISC-V simd mappings

-DLLAMA_FATAL_WARNINGS=ON has to be turned off for all the tests otherwise CI fails

(This can be created a separated issue. I can track the contributor and ping him if you want)

Note 2

One RISC-V board may not be optimal for running all these tests so by the end of RISC-V summit North America, we are expecting more boards to arrive (around mid of November). So this PR can be treated as draft for reviews till then.
