bazel: bump bazel-orfs ef90d6c -> 3a5ddd7, all vendored patches now upstream

All five vendored bazel-orfs patches (0001..0005) landed upstream in
this bump window, in the same order with matching subjects:

  1f4f12e flow.bzl: pull synth into generate_metadata data deps
  b3b19b0 blender.bzl: export blender_supports_pdk predicate
  4b3ae0  orfs_design.bzl: forward blender, silently skip unsupported PDKs
  f4e25a3 environment.bzl: pull src OrfsDepInfo.files into source_inputs
  3a5ddd7 render_gds: trim layerstack before Blender import for fast-turnaround viewer

Drop them all -- `git apply --check --reverse` confirms 0001..0004
match upstream exactly, and 0005's upstream version is the same patch
modulo a small context drift that doesn't matter once the patch isn't
re-applied locally.  patches/bazel-orfs/ goes away entirely.

`bazelisk query //flow/designs/sky130hd/microwatt:microwatt_final_blender_html`
succeeds after the change, so MODULE.bazel resolution still produces
the expected target with no vendored patches.
