end2end: Add an Edid Builder [3/N]

EdidBuilder generates a valid, but synthetic EDID base block (block 0)
for a requested screen resolution and refresh rate. It also allows
embedding a product name string descriptor which can be used to identify
the display later, as it is parsed out by SurfaceFlinger as part of the
gui::StaticDisplayInfo data for a display.

This will be used by the fake HWC3 implementation shortly, and will also
be usedful eventually when the test later injects displays via vkms.

Flag: TEST_ONLY
