Get the l2 cache size via environment variable on confidential VM
...
The CPUID(leaf:2 or leaf:0x80000006) is not supported on some confidential
VMs. As a result the get_l2_size() returns the default 512M which brings
performance issues.
Introduce the environment variable OPENBLAS_L2_SIZE provided by the user
to get the l2 cache size.
