ANDROID: gki_defconfig: enable inline encryption

enable CONFIG_BLK_INLINE_ENCRYPTION and
CONFIG_FS_ENCRYPTION_INLINE_CRYPT

Bug: 137270441
Test: Test cuttlefish boots both with and without inlinecrypt mount
      option specified in fstab, while using both F2FS and EXT4 for
      userdata.img. Also tested by running gce-xfstests on both the
      auto and encrypt test groups on EXT4 and F2FS both with and
      without the inlinecrypt mount option. The UFS changes were
      tested on a Pixel 4 device.
