Add an example under examples/storage/generic_partition_bdl that partitions a raw block device at run time using only the Block Device Layer (BDL) interface. The example obtains a whole-disk BDL (SPI flash data partition by default, or an SD/eMMC card via menuconfig), writes an MBR partition table onto it with the esp_ext_part_tables managed component (fetched via idf_component.yml), then creates a generic-partition BDL for each MBR entry with esp_blockdev_generic_partition_get() and mounts FATFS on the FAT slice and LittleFS on the LittleFS slice.
