Name collision with ArduinoIoTCloud library

[Marcelol52]

Describe the problem

When the ArduinoIoTCloud library is used in the same sketch as this library, compilation fails due to a name collision:

To reproduce

Compile the following minimal demonstration sketch:

#include <ArduinoIoTCloud.h>
#include <Arduino_UnifiedStorage.h>
void setup() {}
void loop() {}

Expected behavior

Library does not pollute the namespace with declarations of common names. When it is necessary to expose a declaration, a distinctive name (e.g., Arduino_UnifiedStorageFileMode::READ) is used.
