If set, Compatibility WAL will not be used.
Currently this flag is set if SQLiteOpenHelper.setWriteAheadLogging(false)
is called before opening the database. Previously this call was ignored
since ENABLE_WRITE_AHEAD_LOGGING flag is only set when setWriteAheadLogging(true)

Using the new constructor can be difficult as it requires an app to
make a decision which version of constructor to use before instantiating
the object. By adding setOpenParams method, apps can keep the old
structure of the code and only add API level check after instantiating
a helper object.

The majority of Manager-style classes already use Context.getUserId()
when making calls into the OS, so clean up the remaining callers to
unify behind this strategy.
This gives @SystemApi developers a nice clean interface to interact
across user boundaries, instead of manually adding "AsUser" or
"ForUser" method variants, which would quickly become unsustainable.

Added Settings.Global.SQLITE_COMPATIBILITY_WAL_FLAGS -
configuration flags for SQLite Compatibility WAL. Encoded as a key-value
list, separated by commas. E.g.:
compatibility_wal_supported=true, wal_syncmode=OFF
SQLiteCompatibilityWalFlags caches the value of
SQLITE_COMPATIBILITY_WAL_FLAGS on first access and keeps it through
the lifetime of the process for consistent behavior across all
connections.

In this mode, only database journal mode will be changed, connection pool
size will still be limited to a single connection.
If enabled, compatibility WAL mode will be used if an app hasn't explicitly
requested journal mode, by calling disable/enableWriteAheadLogging.
Compatibility WAL mode is controlled by debug.sqlite.use_compatibility_wal
property and db_use_compatibility_wal config resource.
Impact on write performance:
On ext4, with WAL, there is approx 300% increase in speed of update operations
On f2fs, with WAL, there is approx 5% increase in speed of update operations
Impact on number of writes:
On ext4, switching to WAL reduces the number of writes by approx 50%.
On f2fs, switching to WAL increases the number of writes by approx 15%.

Internal compatibility testing didn't reveal any issues related to it.
Rationale to not make it specific to low-ram:
1) Consistent behavior from app perspective. close_idle_connections
is a behavioural change and may affect apps relying on undocumented
behavior of connection pooling. Developers can detect problems
without testing on low-ram device
2) Closing idle connections is especially important in WAL mode.
Disabling this feature would become an issue if more apps are
switching to WAL and we would need to re-enable this optimization.

SQLiteDatabase openDatabase -- should take File for first parameter
instead of a String path
SQLiteDatabase.OpenParams.Builder -- make sure the javadocs says what
the default openFlags is and default idle connection timeout
SQLiteDatabase createInMemory -- throw if it has trouble instead of
returning null.
