Use simdjson::pad to pad strings to be parsed by simdjson

See joyeecheung#8 for a reference.

This might also be applicable to

node/src/node_modules.cc

Lines 116 to 120 in 50cfc6c

	size_t json_length = package_config.raw_json.size();
	package_config.raw_json.append(simdjson::SIMDJSON_PADDING, ' ');
	simdjson::padded_string_view json_view(package_config.raw_json.data(),
	json_length,
	package_config.raw_json.size());

There is another place where we are manually padding the buffer, but I am not so sure whether using simdjson::pad is better than the current handling. I'd suggest first time contributors to avoid it unless you can assess the impact between the current approach and using simdjson::pad and find the latter to be preferrable.

@joyeecheung is this issue still open?

I guess only the one in src/inspector_profiler.cc remain now. I am not very sure if it's worth changing, however. So I guess it can be marked as completed.
