Port prjxray to the Virtex-7 family, modelled on Kintex-7, targeting
xc7vx485tffg1761-2 (vc707). Non-breaking for the existing families.
Family registration:
- settings/virtex7.sh, settings/virtex7/devices.yaml
- Makefile: virtex7 in DATABASES/XRAY_PARTS + db-extras-virtex7 targets
- utils/update_parts.py, update_resources.py: virtex7 choice
- CI matrix (Pipeline.yml), Vivado edition (xilinx.sh), README
Architecture adaptations for the HP-bank-only VX part (verified non-breaking):
- update_resources.tcl: fall back to HP banks when no HR banks exist
- XRAY_IOSTANDARD env (default LVCMOS33; LVCMOS18 for virtex7), parameterised
across the fuzzer generate.tcl files
- fuzzers: enable HP-bank (iob18/ioi18) + IOI/HCLK handling for virtex7;
GTX skipped (ffg1761 bonds only ~7 of 14 GTX quads)
- 005-tilegrid: HP/HR bank tile handling; iob18_int INT offset 3->2;
ioi18 AUTO_FRAME; cfg PDRC-2 DRC disable; add_tdb skips unsolved edge tiles;
per-specimen retry for transient FlexLM SIGSEGV under concurrency
- per-family Vivado version gate (virtex7 -> v2020.1.1)
- XRAY_ROI and XRAY_ROI_GRID tuned to a compact CLBLL+CLBLM region
General fixes:
- tools/bitread.cc: fix use-after-free of the mmap'd bitstream (exposed by the
larger Virtex-7 bitstream)
- utils/environment.python.sh: add repo root to PYTHONPATH (PEP 660 editable
install doesn't expose the repo-root utils/ package)

This fixes the problem that when sourcing the vivado settings file the
library search path is modified resulting in non-vivado binaries not working
due to being dynamically linked against the vivado libraries instead of the
system ones.

We are going to use only PERFRAMECRC bitstream from now on because the
tools cannot create a DEBUGBITSTREAM for the zynq7 devices

Identifies the IDCODE and valid configuration frame addresses in the
part. These details are stored in a part-specific YAML file.
