Fix issues found by GC and Fast JIT, refine some codes (#1055)

Browse Source 
Fix handle OP_TABLE_COPY issue
Fix loader handle OP_BLOCK/IF/LOOP issue if type_index is larger than 256
Fix loader handle OP_GET_GLOBAL, allow to change to GET_GLOBAL_64 for
aot compiler similiar to handling OP_SET_GLOBAL
Refine loader handle OP_GET/SET/TEE_LOCAL, disable changing opcode when
source debugging is enabled, so as no need to record the change of opcode
Refine wasm_interp_interp_frame_size to reduce the wasm operand stack usage
