Update sample with new capabilities around functions, parameters, local variables, and live ranges

[wmessmer-msft]

Update sample with new capabilities around functions, parameters, local variables, and live ranges:

• Add the ability to create functions with new .Functions property of the general symbol set
• Add the ability to create local variables and parameters off .Functions
• For each local or parameter, add the ability to create live ranges with locations as string expressions:
  • A straight hex value (e.g.: 7ff23ac)
  • A register with @ as a prefix (e.g.: @rcx)
  • A memory dereference with [] (e.g.: [@rbp])
  • A memory dereference with basic + / - math against a hex nubmer (e.g.: [@rbp + 8])
  • A memory dereference with basic + / - math after the reference (e.g.: [@rbp + 8] + 1c)
