ci : reduce builds in build-xcframework.sh (#27252)
* ci : parallelize platform builds in build-xcframework.sh
The ios-xcode release job builds 7 platform/simulator configurations
sequentially, each with -j $(nproc). Run them with at most 3 concurrent
builds (the release runner has 3 cores), splitting the cores between the
builds (-j 1 each on the runner), so total CPU pressure is unchanged while
the build phase runs about 2.3x faster.
- convert the 7 build blocks into functions (flags unchanged)
- add a run_builds_parallel pool: 3-slot sliding window, per-build logs,
dumps the failing log and aborts on error (background job failures do
not trigger set -e)
- queue the 2-arch builds first so the slower builds occupy the slots early

* pi : add guideline for comments
* cont : disable 5/7 builds
* ci : make build-xcframework.sh builds configurable via CLI args
The script now takes an optional list of builds to run
(ios-sim ios-device macos visionos visionos-sim tvos-sim tvos-device);
with no arguments it builds all of them, as before. The per-build
lists for the build pool, framework setup, static library combining
and xcframework creation are now driven by a single build_spec
lookup instead of four hardcoded (partially commented-out) lists.
release.yml builds only macos and ios-device to cut the build time.
