Add workstation presets: NeXT 1120x832@72, Sun 1152x900 and 1280x1024

Browse Source 
All entries go into GROUP_FIXED_VHZ at the end of the table, so they are
considered only for sources with the matching refresh rate; every other
source is matched exactly as before.

- 1120x832@72 (NeXTstation Color, ADB configuration): 868 total lines,
  62.50 kHz, 90.000 MHz pixel clock (h_total 1440), 1.22 us hsync (110 px),
  3-line vsync; back porches 185/30 and a 45 degree sampling phase tuned on
  hardware. Without it the signal matched 1024x768 and was cropped.
- Sun, timings from the cg6 (GX/TGX) and cg14 (SX) framebuffer PROMs:
  1152x900@66 (94.5 MHz, 1528x937), 1152x900@76 (108 MHz, 1504 total;
  cg6 937 lines @ 76.64 Hz as "1152x900H", cg14 943 lines @ 76.15 Hz as
  "1152x900HS"), 1280x1024@67 (118.125 MHz, 1648x1075, "1280x1024L") and
  1280x1024@76 (135 MHz, 1664x1066, "1280x1024H"). Previously these matched
  1280x960 or the VESA-timed 1280x1024 preset (h_total 1688).

1152x900@66 was verified on a SPARCstation 20 with ZX (Leo) and TurboGX
boards; the other Sun entries are not yet verified on hardware. Mode names
are limited to 10 characters, hence the H/HS/L suffixes.
