16kb: Config rw filesystem based on TARGET_RW_FILE_SYSTEM_TYPE

Browse source 
The TARGET_RW_FILE_SYSTEM_TYPE will contain the rw filesystem
to use. The rw filesystem for the devices can be f2fs or ext4.

If TARGET_RW_FILE_SYSTEM_TYPE is not defined, the default
fs will be f2fs.

Bug: 356425337
Test: $ source build/envsetup.sh
      $ lunch [zumapro]-trunk_staging-userdebug
      $ m
      $ ./vendor/google/tools/flashall -w
Flag: EXEMPT bugfix

// By default this device uses hardware-wrapped keys for storage encryption,
// which is intended to offer increased security over the traditional method
// (software keys). However, hardware-wrapped keys aren't compatible with
// FIPS-140 certification of the encryption hardware, and hence we have to
// disable the use of them in FIPS mode. This requires having two fstab files:
// one for the default mode, and one for FIPS mode selectable via
// androidboot.fstab_suffix on the kernel command line. These fstabs should be
// identical with the exception of the encryption settings, so to keep them in
// sync the rules below generate them from a template file.
