Detailed description

• removed a redundant file for linux arm64
• have separated some functions which helps in understanding code since the native debugger code is #includeed into the debug_native.c
• added a linux-s390x file for native plugin
• added dwarf mapping for sysz architecture
• added register progile for 64 bit s390x and fixed s390 32 bit. ( i have used all the registers that ptrace provides access to).
• right now I just want to check if I am not breaking something

Please ignore the changes in .gitignore and meson.build, I have made those changes so that I can properly build and install to my VM. Hopefully disabling PCRE2 JIT doesnt break other sysz tests
