recovery: Handle devices without /cache partition.

Since we may not have /cache partition on A/B devices, let recovery
handle /cache related operations gracefully if /cache doesn't exist.

(1) Disable the wipe for /cache partition.

(2) Skip wiping /cache while wiping /data (i.e. factory reset).

(3) Disable logging-related features, until we figure out better
ways / places to store recovery logs (mainly for factory resets on A/B
devices).

The Recovery Image

Quick turn-around testing

mm -j && m ramdisk-nodeps && m recoveryimage-nodeps

# To boot into the new recovery image
# without flashing the recovery partition:
adb reboot bootloader
fastboot boot $ANDROID_PRODUCT_OUT/recovery.img

Running the tests

# After setting up environment and lunch.
mmma -j bootable/recovery

# Running the tests on device.
adb root
adb sync data

# 32-bit device
adb shell /data/nativetest/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest/recovery_component_test/recovery_component_test

# Or 64-bit device
adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest64/recovery_component_test/recovery_component_test
