fix(patches): cover every RcppParallel 6.x release with the bundled-TBB patch

This change will:

- Split the patch into per-family files generated against each CRAN release (6.0.0, 6.1.x, 6.2.x), since the TBB read sites move between releases and the old patch did not apply before 6.2.0.
- Pin one exact-version registry entry per release from 6.0.0 to 6.2.1, so 6.0.0-6.2.0 are patched again without matching 5.x or unverified future releases.
- Rewrite the registry reason to lead with the link-order bug and treat the ambient TBB_* handling as a safeguard, now that the build images no longer export those variables.
- Update the in-patch comments that claimed the images still export TBB_ROOT/TBB_LIB/TBB_INC.

-    "reason": "RcppParallel 6.x bundles oneTBB 2022 and builds it with cmake on every platform we ship, so the system-TBB workaround needed for 5.x is gone, but two things still steer the build back to a system TBB. (1) Ambient TBB_ROOT/TBB_LIB/TBB_INC: several build images still export these (build-env-images dropped them, but the images are rebuilt only by cron/manual runs, so a stale image keeps them), and R reads ~/.Renviron *after* the process environment, so no pipeline-side env override can undo it. configure.R then takes the system-TBB branch, install.libs.R symlinks the image's libraries into RcppParallel/lib as absolute paths, and the binary records NEEDED libtbb.so.12 (libtbb.so.2 for the classic Intel TBB on el8/el9) -- it cannot dyn.load on a consumer machine without that exact TBB. Both files are patched to ignore those variables (opt out with BINCRAFT_ALLOW_SYSTEM_TBB=TRUE); install.libs.R needs it separately because R CMD INSTALL runs it outside the src/Makevars rule that passes the configured values. (2) Link order: the bundled branch passes its build dir as '-Wl,-Ltbb/build/lib_release', and gcc expands its own search dirs (/usr/lib64, /usr/lib/<triplet>) into '-L' options ahead of anything forwarded with '-Wl,', so '-ltbb' would still resolve to a distro TBB when one is installed; a plain '-L' puts the bundled dir first. Verified on the current build-env-ubuntu:jammy image (which still exports TBB_INC/TBB_LIB): NEEDED libtbb.so, RUNPATH $ORIGIN/../lib, real libtbb.so.2 in RcppParallel/lib, and the package loads with every system libtbb moved away."
