add kintex7 GTX site_type json

[lgl1227]

I refer to vivado Device to export the GTX part of the xlsx file and convert it to site_type.json through the py script to complete the lack of GTX in the kintex7 series.

In addition, I also found a problem. The wire_intents.json in the kintex7 and artix7 folders seems to be the same. However, i think kintex7's wire_intents.json should be incorrect, at least there is no description of RIOI, RIOB18, etc.

OK, many thanks for the contribution!
I am also currently working on Kintex support, but focusing at prjxray at the moment.
I also have mostly complete fuzzers for GTXE2_COMMON and GTXE2_CHANNEL.
Please coordinate with me to avoid duplicate effort.

I see.
I also followed the prjxray project and found this repository
https://github.com/openXC7/db-workspace-for-kintex7, I discovered your support work for kintex.
I am now more concerned about the source of the files in nextpnr-xilinx-meta. The project says it is derived from the vivado GUI through a tcl script.
However, I didn't find this script.I want to fix the nextpnr-xilinx-meta/kintex7/wire_intents.json file

hi, Would you mind sharing the complete versions of these fuzzers (GTXE2_COMMON、GTXE2_CHANNEL ) so that I can test some GTX cases? I’d be happy to coordinate efforts to avoid any duplicate work.

Hello, the fuzzers are in this branch:
https://github.com/openXC7/prjxray/tree/gtx-support
And the ongoing nextpnr-xilinx implementation (work in progress!) is here:

Thank you very much for providing the fuzzers for GTXE2_COMMON and GTXE2_CHANNEL! I really appreciate your help. I will proceed with testing and coordination based on the versions you shared.
