test/py: mmc: Add tests for MMC device
Add the test cases for mmc commands to test its various functionality such as mmc list, dev, info, rescan, part, ls, load, and save. It also adds different file systems cases such as fat32, ext2 and ext4. Signed-off-by: Love Kumar <love.kumar@amd.com>

+"""
+Note: This test doesn't rely on boardenv_* configuration values but it can
+change the test behavior. To test MMC file system cases (fat32, ext2, ext4),
+MMC device should be formatted and valid partitions should be created for
+different file system, otherwise it may leads to failure. This test will be
+skipped if the MMC device is not detected.
+
+For example:
+
+# Setup env__mmc_device_test_skip to not skipping the test. By default, its
+# value is set to True. Set it to False to run all tests for MMC device.
+env__mmc_device_test_skip = False
