lib: Rename fill_lb_framebuffer to get_lb_framebuffer

Browse source 
Rename `fill_lb_framebuffer` to `get_lb_framebuffer` to better
reflect that it returns framebuffer information.

The new `get_lb_framebuffer` returns a constant pointer to the
framebuffer structure instead of filling a provided structure.
This simplifies the API and avoids an unnecessary memory copy.

The file `edid_fill_fb.c` is renamed to `framebuffer_info.c`
to better match the function it now contains.

Call sites in `coreboot_table.c` and `render_bmp.c` are
updated to use the new API.

TEST=emerge-tanjiro coreboot; check the FW logo is correctly drawn.
