Migrate libmojo repository into libchrome, part 2.

This CL moves following files.
- .gitignore
- Android.bp is merged into libchrome's Android.bp.
- base/android/*
- build/* except build_config.h which is exactly same with libchrome's.
- ipc/*
- mojo/* except mojo/public/tools/bindings/generators/__init__.py
    which is unused and not in chrome repository.
- soong/* into libchrome_tools/
- third_party/{catapult,jinja2,markupsafe,ply}/*
- ui/gfx/{geometry,range}/mojo/*

Then, update several paths/build rules to be adapted.

Bug: 73606903

+  // true means that loading foo.mojom.js will insert a <script> tag to load
+  // bar.mojom.js, if it hasn't been loaded.
+  //
+  // The URL of bar.mojom.js is determined by the relative path of bar.mojom
+  // (relative to the position of foo.mojom at build time) and the URL of
+  // foo.mojom.js. For exmple, if at build time the two mojom files are
+  // located at:
+  //   a/b/c/foo.mojom
+  //   a/b/d/bar.mojom
+  // and the URL of foo.mojom.js is:
+  //   http://example.org/scripts/b/c/foo.mojom.js
+  // then the URL of bar.mojom.js will be:
+  //   http://example.org/scripts/b/d/bar.mojom.js
+  //
+  // If you would like bar.mojom.js to live at a different location, you need
+  // to turn off |autoLoadMojomDeps| before loading foo.mojom.js, and manually
+  // load bar.mojom.js yourself. Similarly, you need to turn off the option if
+  // you merge bar.mojom.js and foo.mojom.js into a single file.
+  //
+  // Performance tip: Avoid loading the same mojom.js file multiple times.
+  // Assume that |autoLoadMojomDeps| is set to true:
+  // <!-- No duplicate loading; recommended. -->
+  // <script src="http://example.org/scripts/b/c/foo.mojom.js"></script>
+  //
+  // <!-- No duplicate loading, although unnecessary. -->
+  // <script src="http://example.org/scripts/b/d/bar.mojom.js"></script>
+  // <script src="http://example.org/scripts/b/c/foo.mojom.js"></script>

+  // <!-- Load bar.mojom.js twice; should be avoided. -->
