Add resize2fs and ability to run resize2fs via GUI

Note: Only works on ext2/3/4 partitions. Only tested on ext4.

We can use this in some cases to resize the data partition if an
incorrect fstab caused recovery to not reserve the 16KB for a
crypto footer.

Sometimes the BoardConfig for a custom ROM does not have the
correct size for the system partition and if the ROM flashes a
raw system image, that image will not take up the full block
device. Running resize2fs can fix the size and may allow more
room in the system partition for customizations like busybox or
a larger gapps package.

Sometimes flashing a factory image may flash userdata with an
image with a file system that does not take up the full size of
the block device (e.g. factory images for the Nexus 6 will flash
userdata with a ~24GB userdata image, wasting ~30GB of space).
Using resize2fs we can easily fix this issue without having to do
a full format data.
