Consolidate vDSO macros and usage
This patch consolidate the Linux vDSO define and usage across all ports that uses it. The common vDSO definitions and calling through {INLINE/INTERNAL}_VSYSCALL macros are moved to a common header sysdep-vdso.h and vDSO name declaration and prototype is defined using a common macro. Also PTR_{MANGLE,DEMANGLE} is added to ports that does not use them for vDSO calls (aarch64, powerpc, s390, and tile) and thus it will reflect in code changes. For ports that already implement pointer mangling/demangling in vDSO system (i386, x32, x86_64) this patch is mainly a code refactor. Checked on x32, x86_64, x32, ppc64le, and aarch64.
