Refactor TextureFormatMap to store an array. std::map lookups are already showing up as a hot spot during some profile trace analysis. We can elimintate these by only doing a single switch at the entry point level to convert the GL internal format to an internal identifier or type info pointer. This change doesn't completely fix the hot spot, since now we are doing multiple switch statements, but it does remove the std::map storage in TextureCapsMap. It replaces it with a flat std::array indexed by angle::Format::ID, and gives us the option in the future to eliminate all by one switch statement. This should allow for a faster texture caps implementation in Vulkan. This also fixes the missing ANGLE format entries for ETC1 compressed formats.
