Add file configuration ComponentProvider support for all SDK extension points

[jack-berg]

#6457 introduced the ComponentProvider SPI as the general purpose mechanism for providing custom SDK extension plugins for file configuration. However, the file configuration implementation now needs to be updated to actually add support for all the various SDK extension plugins. Tracking support below

• SpanExporter, MetricExporter, LogRecordExporter Add file configuration ComponentProvider support for exporters #6493
• Samplers Add file configuration ComponentProvider support for samplers #6494
• Propagators Add file configuration ComponentProvider support for propagators #6624
• SpanProcessor, LogRecordProcessor Processor component provider #6623
• Resource Add file configuration ComponentProvider support for resources #6625
• Update ComponentProvider javadoc to describe usage

For resources, should likely add support for ResourceProvider instead of loading via ComponentProvider since ResourceDeteector is already a first class concept in the specification, and ResourceProvider is the java implementation of ResourceDetector.
