feat: Skia for Android (#1731)

* feat: Call Skia Renderer

* Use default NativePreviewView for Skia

* Render to separate FBO

* It appears once

* Refactor a lot lol

* Pass width/height

* Read width/heights

* Update SkiaRenderer.cpp

* Read stencil/samples

* Use switch for target

* Clear full red

* Update VideoPipeline.cpp

* fix: Use `BorrowTextureFrom` instead of `AdoptTextureFrom`

* Get it to work

* Draw Camera Frame again (only works for first frame)

* glDisable(GL_BLEND)

* Use Frame Buffer again

* Simplify Skia offscreen surface creation

* fix: Get it to kinda work?

* fix: Remove `sampler2D` shader

Only the EXTERNAL_OES one kinda works

* Revert "fix: Remove `sampler2D` shader"

This reverts commit bf241a82f440f5a442f23a2b10329b813e7cdb3e.

* Revert "fix: Get it to kinda work?"

This reverts commit ea6a8784ad8dc7d05e8076591874f021b51dd84a.

* fix: Use Skia for rendering

* Simplify drawing code a lot

* Clean up drawing loop a bit more

* Some docs

* Update SkiaRenderer.cpp

* Surface

* try to use Matrix

* Use BottomLeft as a surface origin again

* Get actual surface dimensions

* Use 1x1 pbuffer instead

* Update SkiaRenderer.cpp

* Update SkiaRenderer.cpp

* feat: Implement Skia Frame Processor (#1735)

* feat: Implement JS Skia Frame Processor

* Update SkiaRenderer.cpp

* push

* Create Frame from C++

* compile

* Compile

* Update VideoPipeline.cpp

* Fix JNI local ref

* Use `HardwareBuffer` for implementation

* feat: Custom `Frame` implementation that uses CPU `ByteBuffer` (#1736)

* feat: Implement JS Skia Frame Processor

* Update SkiaRenderer.cpp

* push

* Create Frame from C++

* compile

* Compile

* Update VideoPipeline.cpp

* Fix JNI local ref

* Use `HardwareBuffer` for implementation

* try: Try to just create a CPU based ByteBuffer

* fix: Fix Java Type

* fix remaining errors

* try fixing FrameFactory

* Use `free`

* fix: Fix scene mode crash on some emulators

* fix: Fix scene mode crash on some emulators

* Fix getting pixels

* fix: Fix buffer not being freed

* Add some docs to `Frame`

* Test Skia again

* Use `getCurrentPresentationTime()`

* Remove `FrameFactory.cpp`

* Update VideoPipeline.h

* Update VideoPipeline.cpp
