LoongArch: Add Kconfig option AS_HAS_EXPLICIT_RELOCS
GNU as >= 2.40 and GCC >= 13 will support using explicit relocation hints in the assembly code, instead of la.* macros. The usage of explicit relocation hints can improve code generation so it's enabled by default by GCC >= 13. Introduce a Kconfig option AS_HAS_EXPLICIT_RELOCS as the switch for "use explicit relocation hints or not".
