Update function discovery and extracting types

[intfinity-zhanteng]

Function discovery

• Undefine large qword arrays from IDA auto-analysis
• Deliberately add_func to improve the output while walking through the function address table from pcln
• Remove rodata segment requirement since it will not work with memory dump

Extract types

• Search lea instruction in reverse order
• Add dynamic search for data section to get name of types
• Add register tagging to each function since the type will be placed in different registers for different functions instead of hardcoding registers
• Add parsing of variables of structs
