Unify names of all architectures, formats, compilers, etc. across RetDec

[PeterMatula]

Different parts of RetDec framework are using different names, formats, cases, etc., for the same information.

Examples:

x86
x86 (or later and compatible)
i386

PowerPC
ppc

x86-64
x86_64

Error: Unsupported target architecture 'x86-64'. Supported architectures: Intel x86, ARM, ARM+Thumb, MIPS, PIC32, PowerPC.

Architecture             : SPARC

"architecture" : {
  [..]
   "name" : "sparc" 
}

Goals:

• Identify sources of these information.
• Normalize them.
• Use them without modifications.

Where:

• Bash scripts.
• JSON config.
• All C++ sources.
• ???

Similarly, we should use a single name for 64b ARM (ARM64 vs AArch64).
