* Revert "Remove GetExternalViewEmbedder from surface (#22272)"
This reverts commit 5419f70f173db1c9f2d5db4c289560e68ce9b77b.
* Revert "Rasterizer is initialized with an external view embedder (#22405)"
This reverts commit f95df42e6e3d80f17c2024e9956768be9416717f.
Cleans up header order/grouping for consistency: associated header, C/C++ system/standard library headers, library headers, platform-specific #includes.
Adds <cstring> where strlen, memcpy are being used: there are a bunch of places we use them transitively.
Applies linter-required cleanups. Disables linter on one file due to included RapidJson header. See https://github.com/flutter/flutter/issues/65676
This patch does not cover flutter/shell/platform/darwin. There's a separate, slightly more intensive cleanup for those in progress.
This is part of a larger effort to expose the difference between GrDirectContext,
which runs on the GPU thread and can directly perform operations like uploading
textures, and GrRecordingContext, which can only queue up work to be delivered
to the GrDirectContext later.
