Fix format support conditions 

This fixes format support tables in formatutils.cpp and formatutilsgl.cpp
to conform to the core and extension GLES specs,
for a large portion of the formats.
ExtsOnly SupportRequirement was enhanced to accept multiple sets of extensions.
Format is supported if all the extensions in one of the sets are available.

Also fixes determining support for extensions based on those formats.

And some fixes to tests which fail due to more strict format support.

// Note 1: This map is used to determine extensions support, which is based on checking support for
// sized formats (this is ANGLE implementation limitation - D3D backend supports only sized formats)
// In order to determine support for extensions which introduce unsized formats, this map would say
// that a corresponding sized format is supported, instead. Thus, if this map says that a sized
// format is supported, this means that either the actual sized format or a corresponding unsized
// format is supported by the native driver.
// For example, GL_EXT_texture_rg provides support for RED_EXT format with UNSIGNED_BYTE type.
// Therefore, DetermineRGTextureSupport checks for GL_R8 support. Therefore this map says that
// GL_R8 (and not RED_EXT) is supported if GL_EXT_texture_rg is available. GL_R8 itself
// is supported in ES3, thus the combined condition is VersionOrExts(3, 0, "GL_EXT_texture_rg").
//
// Note 2: Texture Attachment support is checked also by SupportsNativeRendering().
// Unsized formats appear in this map for this reason. The assumption is
// that SupportsNativeRendering() will not check sized formats in the ES2 frontend
// and the information in unsized formats is correct, and not merged like for sized formats.
// In the ES3 frontend, it could happen that SupportsNativeRendering() would be wrong,
// but this will be mitigated by fall back to CPU-readback in TextureGL::copySubTextureHelper().
//
// Note 3: Because creating renderbuffers with unsized formats is impossible,
// the value of renderbuffer support is actually correct for the sized formats.
//
// Note 4: To determine whether a format is filterable, one must check both "Filter" and "Texture"
// support, like it is done in GenerateTextureFormatCaps().
// On the other hand, "Texture Attachment" support formula is self-contained.
//
// TODO(ynovikov): http://anglebug.com/2846 Verify support fields of BGRA, depth, stencil and
// compressed formats, and all formats for Desktop GL.
