Layouts are now defined in yaml files at latinime/java/assets/layouts. The new system makes simple layouts significantly easier to add.

Many layouts still need to be ported over to the new system and some bugs still remain. The old layout system and XML layouts will need to be removed.

Remove ICS and Holo themes. Remove most png keyboard resources, replacing with xml shapes and colors

With this CL, versionCode, targetSdkVersion and minSdkVersion will be
bumped/set as follows:

       versionCode: 28 -> 30
  targetSdkVersion: 28 -> 30

As far as we know, there should be no user-visible behavior change on
supported OS versions.

Test: manually verified that LatinIME still is functional

This logically reverts my previous CL [1], which moved <uses-sdk />
from AndroidManifest.xml to AndroidManifest_SdkVersion.xml, which was
later accidentally removed during Android.bp migration [2].

Since gradle support in LatinIME is still experimental and not used in
official build, it is OK to keep it broken for a while.  A more
important problem right now is letting LatinIME target API 28.

As the first step to let LatinIME target SDK 28, <uses-sdk> will be
revived in AndroidManifest.xml

These tests are supposed to run even withotu @RunWith annocation, but
for better consistency we should have it there.

This should be the most convenient way for both make build and Android
Studio build to share the same version code.

Basically Android Studio does want targetSdkVersion to be specified in
build.gradle rather than AndroidManifest.xml.  To make both make build
and Android Studio build happy, this CL splits <uses-sdk /> from the
main AndroidManifest.xml to a different file and let them merged in
make build.

There should be no behavior change.

InstrumentationTestCase and ActivityInstrumentationTestCase2 are
deprecated.  This CL rewrites tests that rely on those deprecated
classes by using Android Testing Support Library.
