bazel: add bazel-orfs support to all public-PDK platforms and designs

Enable nangate45, gf180, ihp-sg13g2, and sky130hs platforms in
MODULE.bazel and flow/BUILD.bazel. Create BUILD.bazel files for all
design source directories and platform design directories. Unblock
previously blocked asap7/sky130hd designs that only needed src/
BUILD.bazel files.

Smoke-tested: gcd_test passes on all 4 new platforms.

Skipped platforms without public PDK: gf12, gf55, rapidus2hp.
