fix(remote-config): support restored Node.js capability bits

[mtoffl01]

Motivation

DataDog/dd-trace-js#10573 restores the legacy per-setting APM_TRACING_* capability bits alongside SDK_CONFIGURATION. Node.js v6.17.0 and v6.18.0 advertise only SDK_CONFIGURATION, while the v6.19.0 release line will advertise both families, but continues to consume only sdk_config.

System-tests previously treated the presence of any legacy bit as proof that a tracer consumed lib_config. This caused the dynamic-configuration parametric suite and debugger in-product enablement tests to send the wrong payload shape.

Changes

• Treat the presence of SDK_CONFIGURATION as authoritative for Node.js after APM_TRACING registration, including when legacy capability bits are also present.
• Preserve the existing libdatadog bit-collision safeguard for other tracers.
• Use SDK_CONFIGURATION to select sdk_config for Node.js 6.17.0 and later. Preserve the historical capability masks: 6.17.0–6.18.x advertise only SDK_CONFIGURATION, while 6.19.0+ also advertise the restored per-setting bits.
• Require SDK_CONFIGURATION plus the restored legacy bits on the 6.x release line from v6.19.0. Allow 7.0.0 prerelease main builds to advertise those extra bits without requiring them before dd-trace-js#10573 lands.
• Add regression coverage for the mixed Node.js capability set and the equivalent PHP interpretation.

Validation

Tested locally against the exact system_tests_binaries artifact produced by dd-trace-js#10573, reporting nodejs@7.0.0-pre.
