Subject: [PATCH] android: Add a splash screen.

Using `expo-splash-screen`'s Android-specific setup
instructions [1], but with some important exceptions:

- We don't (currently) intend to actually use
  `expo-splash-screen` [2], which means

  - Don't name a color "splashscreen_background". The API looks for
    that particular resource name. But we don't like its
    capitalization, which is inconsistent with the surrounding
    names [3].

- Don't use an image; we can add one later if we want.

- Don't do anything marked "optional".

- Don't go through a `splashscreen.xml` file; this extra indirection
  is unnecessary for us [4].

- Don't add an `android:theme="@style/AppTheme"` attribute to the
  `activity` element in our `AndroidManifest.xml`; it's redundant,
  with the same attribute already present in its parent
  `application` element.

What's left is extremely small, and hard to describe, really, as
"adding a splash screen". We're setting a background color, which
will be what shows before our React elements have mounted and are
showing.
