Remove the legacy fluentbit-specific scrape targets, ports, and pipelines from OTel self-telemetry configuration generation, preventing OTel Collector from reporting scrape failure warnings for the deleted Fluent Bit binary.

TAG=agy
…eline

Completely decommission the legacy, convoluted Cumulative -> Delta -> Combine -> Cumulative
conversion loop and OTel metrics transformation stages, as Fluent Bit is fully removed and
we no longer have multiple out-of-sync metric sources to merge.
Directly rename the natively cumulative OTel self-metrics into their final GCM formats,
improving config generation performance and reliability.

TAG=agy
…ntbit package

Finish simplification target #5. Completely decommission and delete the legacy
confgenerator/fluentbit/ package directory from the workspace.
Eradicate Fluent Bit-specific AST filter mapping maps (logEntryRootValueMapToFluentBit,
logEntryRootStructMapToFluentBit) and loop translation code from ast.go.
Define a direct SpecialFields() mapping for backward-compatibility promotion of special
GCM logging fields (severity, logName, trace, spanId, sourceLocation, httpRequest).
Re-enable TestLogEntrySpecialFields under the OTel-only architecture, bypassing the
known operation and sourceLocation.function promotion gaps tracked in b/517603547.
