The pointer addresses passed in the wasm plugin should have a value range of uint64.
After calling the import method of the wasm plugin, deepflow-agent will check the memory boundary and perform check_memory. The memory limit in wasm is 4G (the limit for 32-bit programs). When we perform check_memory, we receive a pointer address, the original parameter type is i32, but it should actually be u32.
