LoongArch: Add new option annotate for objdump

Adds 'objdump -dM annotate' to display disassembly with annotations for LoongArch dbar instructions.

This patch introduces a new ‘annotate’ option for the LoongArch objdump tool. When used with ‘-dM annotate’, it will display disassembly along with specific annotations for ‘dbar’ instructions, providing more detailed insight into their usage and behavior.

In Details

This patch adds a new disassembly annotation option to objdump for the LoongArch architecture. The 'annotate' mode specifically targets 'dbar' instructions, providing meta-information about their operands or behavior during disassembly.

For Context
objdump
A utility that displays information from object files, including disassembly of machine code.
LoongArch
