bazel: bump ORFS to pick up the single-writer 1_synth.sdc fix

ORFS afad87da includes OpenROAD-flow-scripts#4333: yosys' synth.tcl no
longer copies SDC_FILE over 1_synth.sdc, so synth_odb.tcl's write_sdc
is the sole writer and no longer fails when bazel inputs are read-only
(RBE; cp preserves the missing write bit). Follow-up to #10818.

Drop 0035-orfs-bazel-orfs-visible-non-root.patch: upstreamed, @orfs now
declares its bazel-orfs bazel_dep non-dev.

Verified with chmod a-w test/orfs/gcd/constraint.sdc to emulate RBE's
read-only inputs: //test/orfs/gcd:gcd_synth fails before this change
with "cannot write file .../1_synth.sdc" and passes after.
