[Impeller] add additional setup method that caches more pipelines, warms internal shader code (#50521) Part of https://github.com/flutter/flutter/issues/138236 Fixes a number of issues related to startup performance by adding an "InitializeCommonlyUsedShadersIfNeeded" method to content context. On the first frame of a flutter application renders, the backend will populate the glyph atlas for the first time. On the Vulkan backend, this executes vkCmdCopyBufferToImage. The first time this runs, Arm Mali drivers will generate an additional shader program. Creates a 1x1 texture and sets the contents to force this code to compile eagerly.  The first time a render pass is constructed, a shader is complied. This does not seem to depend on the properties of the render pass, so we just create a trivial one and submit it.  Finally there are a few missing shader variants. Lets just go ahead a populate that cache a bit more
Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter's core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.
