video: edid: guard standard timings EDID expansion behind kconfig

Since EDID only indicates supported standard timings, a large table with
detailed timing information is necessary, consuming significant space. To
mitigate this, the table is made configurable via kconfig, allowing it to
be excluded when not needed.
