Add a README file for RISC-V specific kernel selftests under tools/testing/selftests/riscv/. This mirrors the existing README for arm64, providing clear guidance on how the tests are architecture specific and skipped on non-riscv systems. It also includes standard make commands for building, running and installing the tests, along with a reference to general kselftest documentation.

KSelfTest RISC-V
================
- These tests are riscv specific and so not built or run but just skipped
completely when env-variable ARCH is found to be different than 'riscv'.
- Holding true the above, RISC-V KSFT tests can be run within the
KSelfTest framework using standard Linux top-level-makefile targets:
$ make TARGETS=riscv kselftest-clean
$ make TARGETS=riscv kselftest
or
$ make -C tools/testing/selftests TARGETS=riscv \
INSTALL_PATH=<your-installation-path> install
or, alternatively, only specific riscv/ subtargets can be picked:
$ make -C tools/testing/selftests TARGETS=riscv RISCV_SUBTARGETS="mm vector" \
INSTALL_PATH=<your-installation-path> install
Further details on building and running KSFT can be found in:
