Add T4F_C4UB_N3F_V4F and T4F_C4F_N4F_V4F formats

[jopadan]

Proposal to add glInterleavedArrays vertex array standard formats:

• T4F_C4UB_N3F_V4F 12 * sizeof(GLfloat) 4x3 matrix
• T4F_C4F_N4F_V4F aligned 16 * sizeof(GLfloat) 4x4 square matrix

example structures of added standard vertex formats:

struct T4F_C4F_N4F_V4F
{
   vec::f32<4> tex;
   col::f32<rgbaf32> col;
   vec::f32<4> nor;
   vec::f32<4> pos;
};

struct T4F_C4UB_N3F_V4F
{
   vec::f32<4> tex;
   col::u8<rgba8888> col;
   vec::f32<3> nor;
   vec::f32<4> pos;
};

To add new formats would require creating an extension and getting vendors to implement that extension in their drivers. If you can convince them to do that you're welcome to, but this PR literally accomplishes nothing other than adding a few lines to the XML.
