Remove Linux sysroot dependencies of SVE PT macros

Summary:
SVE elf note data requires SVE PT macros for reading writing data. Same macros are used by Linux ptrace SVE register access.
This patch makes necessary changes to lldb/source/Plugins/Process/Linux/LinuxPTraceDefines_arm64sve.h in order to make them sysroot independent.
