Currently, several examples do not explicitly state their component
dependencies, relying instead on the default behavior that includes all
registered components and commonly required ones in the build.
Explicitly adding component dependencies can reduce build time when
set(COMPONENTS main) is used.

* If esp_vfs_spiffs_register is called with an explicit partition
label, other SPIFFS functions (info, format, unregister) must be
called with the same label.
* On the other hand, if label was NULL in the call to
esp_vfs_spiffs_register and the first matching partition was used,
calls to the rest of the SPIFFS functions should be done with NULL
partition_label argument.
Fix the Doxygen documentation. Update the example accordingly, in case
a user modifies "partition_label" value in esp_vfs_spiffs_conf_t conf
initializer.
