…RecordBuilder150Incubator

Add 'deprecation' to @SuppressWarnings on convertExtendedAttributes method to
handle OtelDeprecatedApiUsage errors for deprecated ExtendedAttributes,
ExtendedAttributesBuilder, and ExtendedAttributeKey usage. This is needed to
support applications still using the EXTENDED_ATTRIBUTES feature.

SDK 1.60.0 sets the isTraceIdRandom bit in trace flags for randomly generated
trace IDs, changing the value from 0x01 to 0x03. Update MDC tests to use
span.getSpanContext().getTraceFlags().asHex() for expected values.

…new API method

Compute the random trace ID flag from the byte value directly instead
of delegating to the application's TraceFlags.isTraceIdRandom() which
does not exist in API versions < 1.60. The previous implementation
created a bytecode reference that muzzle detected as missing, causing
all opentelemetry-api bridge instrumentation modules to be disabled.

…tomizer interface change

DeclarativeConfigurationCustomizer is no longer a functional interface
in SDK 1.60.0 (it now has addSpanExporterCustomizer, addMetricExporterCustomizer,
and addLogRecordExporterCustomizer in addition to addModelCustomizer).
Replace the lambda with an anonymous class implementation.

…terface change

DeclarativeConfigurationCustomizer is no longer a functional interface
in SDK 1.60.0. Replace lambdas with anonymous class implementations in
SpanLoggingCustomizerProviderTest and ResourceCustomizerProviderTest.

Filter out otel.sdk.* metrics in metric assertions to avoid coupling
tests to SDK internal self-diagnostics metrics which changed in 1.60.0.

The otel.experimental.config.file property is deprecated in SDK 1.60.0
and will be removed after 1.62.0. Rename all usages to otel.config.file.
Also add the SDK deprecation warning to IGNORED_WARNINGS in the Spring
smoke tests since the SDK may still emit it during initialization.

SDK 1.60.0 emits self-diagnostics metrics, so the exported metrics list
contains more than just the test metric. Use anySatisfy instead of
checking exact size to avoid coupling to SDK internal metrics.

SDK 1.60.0 has a bug in maybeConfigureFromFile() where the condition
is inverted, causing it to warn about otel.experimental.config.file
being deprecated even when the property is not set.
