Avoid temporary dependency maps during Skyframe deletion (#32067) DeletingNodeVisitor queries the existing NodeBatch directly instead of allocating a filtered map of dependency entries for each deleted node. Nodes with no dependencies retain the existing behavior, and reverse-dependency removal and interrupted deletion still use the same graph entries. In the original fixture deleting one million nodes with one dependency, allocation fell from 592.4 to 376.6 MB and median time from 737.7 to 664.2 ms. Original SkyframeTests passed 1,473 cases (6 skipped). The complete patch matches the original and git diff --check passes upstream. @fmeum Closes #32067 COPYBARA_INTEGRATE_REVIEW=https://github.com/bazelbuild/bazel/pull/32067 from dzbarsky:dzbarsky/upstream-bazel-148 bed4b20e89d570ccff3f9b9d895d5c0dbdbce5b1 PiperOrigin-RevId: 1008284342 Change-Id: Ia02fba8bcc17ba89d42569fe0b6a418eeadd58de
