Previously, a fixed size buffer was allocated each time a call to
`computeSha256DigestForLargeFile` was made. This causes
undesirable performance issues. This change allocates a buffer
per apex/module-update session instead.
To fix this, that method is amended to take in a buffer passed
in by the caller instead.
To aid in the usage of this API, a new method called
`createLargeFileBuffer` is introduced to help callers allocate
a pre-determined buffer size to be passed into the SHA
computation method based on whether the device is low RAM
device or not.
Subsequent RSS benchmarking shows that this helps to
significantly lower the RSS high watermark (HWM) for
the `system_server` process into just noise.

In current desgin, the confgis for cutout and rounded corner are based
on the original display size. If the display resolution is overridden,
cutous and rounded corners will be drawn in incorrect places with
incorrect size.
We should load the cutout & rounded corners with the orignal display
size and then scale the results with the display ratio which is
calculated by dividing current size with original size.
Bug: 209592558
Test: manual:
1. Go Settings-> Display-> Screen Resolution
2. Switch between FHD+ and QHD+
3. Check if the cutout and rounded corner looks the same as they
are in the original display size.
Test: manual:
1. adb shell wm size 1080x2340
2. Check if the cutout and rounded corner looks the same as they
are in the original display size.

Add the ability to configure NTP port for tests via the command line and
the associated plumbing / knock-ons.
In-progress CTS tests will run a fake NTP server on the device itself.
Binding to NTP's default port of 123 is restricted. Therefore, we need
to be able to override the port for tests.

On low RAM devices, there can be potentially OOM issues when
APEXs are too large, causing large buffers to be allocated when
computing the SHA256 digest of those APEX packages.
This change introduces the usage of DigestInputStream with
different buffer sizes according to the state of device (whether
it is a low ram device or not) to cap the memory usage.
Buffer size is currently derived experimentally at either 1kB or
1MB.
