chore: bump yosys to 0.62.bcr.2 and drop carried patches

The three yosys patches we carried (visibility, hdrs, tcl9-mp-to-ubin)
all landed upstream in BCR yosys 0.62.bcr.2 via
bazelbuild/bazel-central-registry#8636. Bump to that version and drop
the single_version_override blocks across all six root modules
(root, gallery, test/downstream, mock/chisel, orfs, chisel) plus
delete the patch files.

Mirrors the cleanup OpenROAD did in The-OpenROAD-Project/OpenROAD#10237.
