RISC-V: Factor out immediate checking functions from assembler_riscv.inline.hpp

The call-point to 'is_imm_in_range', 'is_unsigned_imm_in_range' and 'is_offset_in_range' in assembler_riscv.inline.hpp could to be replaced with shared code.

For 'is_imm_in_range', if align_bits = 0, then the call point can be changed to call 'is_simm'. If align_bits = 1, then an additional summation judgement is added to determine if it is a multiple of 2. For 'is_unsigned_imm_in_range', we can first determine if it is greater than 0, and then call 'is_uimm' further. 'is_offset_in_range' can be changed directly to call 'is_simm'. This patch also refactored for is_valid_riscv64_address and movptr.

This patch removed the original functions from assembler_riscv.inline.hpp and defined some fixed-width judgment functions based on the number of immediate or offset bits in the spec[1]. At the same time, we also adjusted two includes to fix the compilation error after the modification.

This patch also renames the function 'operand_valid_for_add_immediate' to 'operand_valid_for_add_sub_immediate' to make it consistent with its usage.

Finally, this patch modified the return value in os::non_memory_address_word to avoid an imm64 value of -1 in MacroAssembler::movptr.
