feat(usb_device_example): Create per-target sdkconfig.defaults

    - Select "SDMMC CARD" for "Storage Media Used"
    - Select "SD/MMC bus width" — "4 lines (D0 - D3)" or "1 line (D0)" (see `CONFIG_EXAMPLE_SDMMC_BUS_WIDTH_1`)

+3. In the source code: See the initialization of ``sdmmc_slot_config_t slot_config`` structure in the example code.
 
 By default, this example uses 4-line SD mode, utilizing 6 pins: CLK, CMD, D0 - D3.
