vold: use __ANDROID_API_Q__ instead of pre_gki_level

The name "pre_gki_level" is causing some confusion because not all
devices launching with Android R are subject to the GKI requirement.
(See b/161563110#comment11.) E.g., devices that use a 4.14-based kernel
are exempt from GKI. However, the encryption requirements still apply.

Just use __ANDROID_API_Q__ directly instead.

No change in behavior.

EncryptInPlace: ensure that backup superblocks get encrypted

Block groups with EXT4_BG_BLOCK_UNINIT still have backup superblocks
(and backup block group descriptors). Fix EncryptInPlace to encrypt
these backup superblocks rather than leave them unencrypted.

Previously leaving the backup superblocks unencrypted didn't cause any
problems, but due to system/core commit 72abd7b246f7 ("Try to recover
corrupted ext4 /data with backup superblock") it is causing problems.

Use C++'s built-in mechanism for one-time initialization rather than
implement it ourselves in a way that isn't thread-safe.

(It doesn't *actually* need to be thread-safe, since all callers of this
run under ACQUIRE_CRYPT_LOCK. But that's not easy to verify.)

vold: remove checkEncryption

The testing-only "checkEncryption" command has been replaced with
VtsKernelEncryptionTest [1]. In particular, the metadata encryption
documentation [2] no longer mentions checkEncryption but rather
recommends running VtsKernelEncryptionTest. Also, checkEncryption
hasn't really been maintained, and it has some known bugs; it's unclear
that many people ever really used it.

So, just remove it.

vold: only allow emmc_optimized on eMMC storage

The emmc_optimized encryption flag is specifically designed for the
limitations of inline encryption hardware that follows the eMMC
standard.  It isn't appropriate to use on other types of storage.
So, make vold enforce that it's not used on other types of storage.

Bug: 160639344
Test:
  - Enabled emmc_optimized on Cuttlefish and verified it no longer boots
  - Using a modified version of this change, verified that
    IsEmmcStorage() works as expected on various devices including
    Cuttlefish, Cuttlefish booted in GSI image mode, a device with eMMC
    storage, and a device with UFS storage.
  - Verified that VtsKernelEncryptionTest still passes

Configure backing device max_ratio for FUSE filesystems.

By default FUSE filesystems have a max_ratio of 1%, meaning only 1% of
dirty pages on the system can belong to a FUSE filesystem before we
start writing back pages (and throttling, if writeback can't keep up).
This limit is useful for untrusted filesystems, but in our case, we
trust the FUSE filesystem. Since FUSE writes result in writes to the
lower filesystem, FUSE should take at most 50%. Let's start with
changing max_ratio to 40%, to avoid needless throttling.

Unmount public volume if FUSE mount fails

Sometimes, during early boot, a public volume may be created before
the user is unlocked and the mount may fail. This mount failure does
not revert the lower fs mounts (sdcardfs and vfat). Subsequent
mount attempts will then fail because we'd attempt to mount vfat on
already mounted /mnt/media_rw/<volname>

Test: Resilient to an artificial sleep in
StorageManagerService#completeUnlockUser to
