TEST ONLY: SymDB extractor without throttle (regression detection check for #5776)

[p-datadog]

JIRA: DEBUG-5668

Summary

Do not merge. This is a sibling-branch test for #5776.

Branches from #5776's tip and reverts only the throttle implementation in lib/datadog/symbol_database/extractor.rb + sig/datadog/symbol_database/extractor.rbs. The benchmarks and helper additions from #5776 are kept.

The point is to verify that the benchmarks added in #5776 actually catch a throttle regression, by running CI against a branch where the throttle has been removed.

What's removed vs #5776's tip

• SLEEP_EVERY_N_MODULES = 100 constant
• SLEEP_SECONDS = 0.001 constant
• private_constant :SLEEP_EVERY_N_MODULES, :SLEEP_SECONDS
• The sleep SLEEP_SECONDS if (seen % SLEEP_EVERY_N_MODULES).zero? call (and its seen counter) in collect_extractable_modules
• Matching RBS lines

What to check in CI

Compare CI output here vs #5776:

1. symbol_database_background_impact — p99_ratio_treatment_over_baseline should jump from ~1.05 (PR 5776 with throttle) to well above 1.5 (this PR). The in-script enforce_requirement gate at threshold 1.50 should fire exit 1.
2. symbol_database_baseline_matrix — the 100%-arm rps_drop should jump from ~8% to materially higher. Lower-baseline arms are noisier in microbenchmark form (documented limitation), but should also shift.
3. bp-runner microbenchmarks (gitlab) — large ops/sec drop on the workload arms of both benchmarks vs master.
4. symbol_database_extraction — wall_time_seconds should drop ~2x (no per-chunk sleep) and cpu_percent should approach 100%. Memory should be unchanged.

Cleanup
