libs: video-format: Refine the video format mapping.
Improve the mapping between va format and gst format. The new map will be generated dynamically, based on the query result of image format in VA driver. Also consider the ambiguity of RGB color format in LSB mode.

/* LSB and MSB video formats definitions are unclear and ambiguous.
|

*
|

* For MSB, there is no ambiguity: same order in define, memory and
|
||||
* CPU. For example,
|
||||
*
|
||||
* RGBA is RGBA in memory and RGBA with channel mask R:0xFF0000
|
||||
* G:0x00FF0000 B:0x0000FF00 A:0x000000FF in CPU.
|
||||
*
|
||||
* For LSB, CPU's perspective and memory's perspective are
|
||||
* different. For example,
|
||||
*
|
||||
* RGBA in LSB, from CPU's perspective, it's RGBA order in memory,
|
||||
* but when it is stored in memory, because CPU's little
|
||||
* endianness, it will be re-ordered, with mask R:0x000000FF
|
||||
* G:0x0000FF00 B:0x00FF0000 A:0xFF000000. In other words, from
|
||||
* memory's perspective, RGBA LSB is equal as ABGR MSB.
|
||||
*
|
||||
* These definitions are mixed used all over the media system and we
|
||||
* need to correct the mapping form VA video format to GStreamer
|
||||
* video format in both manners, especially for RGB format.
