As seen in the example given, when attaching an SRGB/RGB texture view is
created from an alternate RGB/SRGB texture, then attached as a framebuffer,
rendering will gamma correct wrongly and querying
GL_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING will return GL_LINEAR for an SRGB
backed frame buffer.

This is causing AA renders to be too dark as in our unreleased project, among
many other subtle colour issues.

Tested on latest 11.3 (git-9d9965c from oibaf) and seen on older drivers as
well.
$ g++ TextureViewFramebufferSRGBTest.cpp.cpp $( sdl2-config --cflags --libs )
-lGL
This reproduces on Mesa AMD and swrast.
