PoC: Update Jaeger exporter to rely on the SDK for batching and NoOp performance

[MrAlias]

Changes

• Remove Jaeger exporter dependency on cloud.google.com/go by removing the use of the provided Bundler.
• Stop batching spans that have been sent to the Jaeger exporter for export. Instead transform and export the span during the call to ExportSpans and rely on the BatchSpanProcessor for batching.
• Remove the flush function from the Jaeger exporter. The exporter no longer maintains spans between calls to ExportSpans so there is no use for a flush function.
• Update the return value for all the convenience creation functions (InstallNewPipeline and NewExportPiepeline) to not return the now unneeded flush function.
• Remove the WithBufferMaxCount option. The Jaeger exporter no longer bundles.
• Remove the WithBatchMaxCount option. The Jaeger exporter no longer bundles.
• Remove the WithDisabled option. Unregistered the wrapping span processor from the TracerProvider or do not set a global TracerProvider for instrumentation to use.
• Remove the WithSDKOptions option and instead pass these options directly to the convenience creation functions.
• Remove the Option type. There is not configuration needed to be set for the Jaeger exporter other than endpoint configuration (which is handled by the respective uploader configuration).
• Remove the locking for the Jaeger exporter, instead unify on using context and channels to signal when an export needs to be canceled.
• Remove the Process type. This is leftover from Remove process config for Jaeger exporter #1776.
• Add benchmark test to track resources used in ExportSpans

Going to try and break this into smaller PRs.
