add riscv64 support and CI

[HeliC829]

This PR adds RISC-V 64 build support for ISA-L crypto and CI.
Since AES has no base aliases available, aes_self_tests in fips will be disabled on RISC-V 64.

Pull Request Overview

This PR adds RISC-V 64-bit architecture support to the ISA-L crypto library by configuring build files and source lists for the new architecture. Since AES has no base aliases available on RISC-V 64, the AES self-tests are disabled for this architecture in the FIPS module.

• Adds RISC-V 64 CPU detection and conditional compilation in autotools configuration
• Includes appropriate source files for cryptographic modules (SHA, MD5, etc.) on RISC-V 64
• Excludes AES self-tests from FIPS on RISC-V 64 due to missing base aliases

Hi @HeliC829. Could you work with your colleague @sunyuechi to add RISC-V testing to CI, similar to the way it's done in ISA-L library? Thanks!

Sure.

@HeliC829 will submit the PR for CI support, and I will maintain the related machines (we need to request the project token via email).

I've added CI in #161.

Thanks for combining the PRs. Could you update README to indicate RISC-V is now supported too? Look at "Prerequisites" section. Also update Release notes, section 3. You can add a bullet point below v2.26, saying RISC-V supported is now added. Please, rebase your PR on top of latest "master" branch. Thanks!

I've rebased and added some note in Release notes and README.

Thanks! I will merge the two last commits into the commit that is adding the RISC-V support to the library, to reduce the amount of commits, if that's OK to you.
