Add minimal GL support for protected backend textures
Bug: b/205516620
Internally, Skia does not have full GL support for protected backend
textures. But there are some clients who know that they need to create
one so that they can render a protected buffer into it. Plumb in support
for clients calling GrDirectContext::createBackendTexture.
GrGLDefines.h:
- Add macros for querying whether a context is protected
GrGLCaps:
- Check whether the GL_EXT_protected_textures extension is present and
the context supports protected.
GrGLGpu:
- Remove failure cases for GrProtected::kYes. Instead, pass the value
down to createTexture where we then set the parameter in GL.
