Dr Jonathan Richard Robert Kimmitt 39f5de415d Add Virtex-7 (xc7vx485t) family support 
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)

Rick Altherr 53d7f1f80b lib: xc7series: shorten accessor names 
_address suffix on accessors is unnecessary and somewhat inaccurate.
The returned values are indices rather than frame addresses.

Rick Altherr a4858be23a lib: accessor to get contents of a memory-mapped file as bytes 
MemoryMappedFile's data() method returns a void* as it has no idea what
type the contents are.  Viewing it as bytes is a very common operation
so add a convience method that wraps the pointer in a Span<uint8_t>.
