[FFmpeg-devel,1/3] avutil/pixfmt: Add EBU Tech. 3213-E AVColorPrimaries value

From: Raphaël Zumer <rzumer@tebako.net>

This is an alias for JEDEC P22.

The name associated with the value is also changed
from "jedec-p22" to "ebu3213" to match ITU-T H.273.

this value was already present, this is just a rename

I'd do the opposite, similarly to what is done for AVCOL_PRI_SMPTEST428_1

   AVCOL_PRI_EBU3213     = 22, ///< JEDEC P22 phosphors, EBU Tech 3213 E
   AVCOL_PRI_JEDEC_P22   = AVCOL_PRI_EBU3213,

I think it counts as a new enum value (variant), even though it aliases 
another.

I initially wrote "rename", but reworded the commit message based on 
James Almer's comment:

Will do. I will also replace internal usage of JEDEC_P22 with EBU3213 
elsewhere.

I just noticed I missed the same comment (and a few others) in JA's 
review earlier, sorry about that. Will apply all corrections in my next 
revision.
