cpuid_zarch/hwcaps: add documentation and dump hwcaps in init
Add pointers to the definition of the hardware capability flags in glibc and describe how they relate to the levels CPU_Z13 and CPU_Z14 for optimized kernels. To aid identifying available hardware capabilities and in debugging potential build issues, dump their value in dynamic_arch_init() when OPENBLAS_VERBOSE is set to 2 or higher.

s390x: use DYNAMIC_ARCH's cpu detection for compile-time choice
On s390x, the run-time detection for DYNAMIC_ARCH and the compile-time choice in cpuid_zarch use different methods for identifying the supported CPU features. To make cpuid_zarch future-proof and both easier to maintain, switch cpuid_zarch to the same mechanism as DYNAMIC_ZARCH (i.e., derive the supported CPU features from hwcap flags) and share code between both (in a new header cpuid_zarch.h).
