Improve portability

Improve support for RISC-V arch in volk_gnsssdr via cpu_features (updated to c919e9a).
Set BLA_PREFER_PKGCONFIG if not defined by the user, helps to find lapack in some archs (e.g., riscv64)
Fix for Fedora/OpenSUSE, which do not install cpu_features along volk.
Remove volk_gnsssdr_8ic_s8ic_multiply_8ic kernel since it was problematic in some archs
Improve Python detection
Fixes for GCC 13
Remove ENABLE_GENERIC_ARCH configuration option and old ARM detection mechanism
Update gtest to 1.13.0
Add CI jobs for volk_gnsssdr and gnss-sdr in non-x86 archs
