Part of #9587.

Added: perl_bench (core Benchmark via DxBench::run_benchmarks) and ruby_bench (benchmark-ips 2.14.0, pinned sha256 in ruby/coverage/pins.bzl, fetched by the existing ruby_coverage extension as @dx_ruby_bench_gems). Both are <lang>_test targets tagged dx-bench and manual, writing dx-bench.json in seconds. Named *_bench to match the merged macros (#9632).

Tested locally on Linux: dx bench //perl/tests/bench:sum_bench and //ruby/tests/fixtures/bench:sum_bench (families workspaces) print results; //ruby/rules:all //perl/rules:all //ruby/coverage:all pass. Local bench needed -- --zip_undeclared_test_outputs on this host, otherwise dx reports no dx-bench.json (separate problem, not touched). Consumer and nested-Bazel tests were not run.

Also added: dart_bench (package:dx_bench runBenchmarks over benchmark_harness 2.4.0, hub @dx_dart_bench_deps from the pinned dart/rules/bench/pubspec.lock). //dart/tests/bench:sum_bench passes locally (dx-bench.json written). //dart/rules:wrapper_contract_tests could not be built locally (remote cache error on libz-sys even without cache). Consumer and nested-Bazel tests were not run.

Also added: php_bench (phpbench 1.7.0 phar, sha256 pinned in php/toolchain/pins.bzl, repo @dx_phpbench). benches lists phpbench files; a PHPUnit runner executes the phar and writes dx-bench.json in seconds per revolution. @rules_dx_php//php/tests/bench:sum_bench, //php/toolchain:metadata and //php/rules:wrapper_contract_tests pass locally.

Remaining for #9587:

• ruby_fuzz_test (ruzzy needs a native extension built against libFuzzer) and php_fuzz_test (no pinned php-fuzzer phar)
• julia_bench: BenchmarkTools depends on Statistics, an upgradable stdlib in Julia 1.12; rules_julia precompiles with @stdlib first on the load path, so the registry copy yields no cache and the build fails. Skipped; needs a rules_julia change
• lua_bench: no maintained Lua harness found
• docs/support-matrix.md has no bench or fuzz content; generation could not build locally (remote cache error), not regenerated
