Refactor copy callstack feature (#4401)

- Change `WAMR_ENABLE_COPY_CALLSTACK` to `WAMR_BUILD_COPY_CALL_STACK`, as
  `WAMR_BUILD` is the prefix for a command line option.
- Change `WAMR_ENABLE_COPY_CALLSTACK` to `WASM_ENABLE_COPY_CALL_STACK`, as
  `WASM_ENABLE` is the prefix for a macro in the source code.
- Change `CALLSTACK` to `CALL_STACK` to align with the existing
  `DUMP_CALL_STACK` feature.
- Continue using `WASMCApiFrame` instead of `wasm_frame_t` outside of
  *wasm_c_api.xxx* to avoid a typedef redefinition warning, which is
  identified by Clang.
