[DI] Remove ConfigureBuilder and add implementation factory helpers

[CodeBlanch]

Changes

• Adds a few standard helper extensions which were missing that would force users to call ConfigureBuilder.
• Removes ConfigureBuilder.

Note: ConfigureBuilder functionality is still available by casting the builder to either IDeferredTracerProviderBuilder or IDeferredMeterProviderBuilder.

Public API Changes

OpenTelemetry.Extensions.DependencyInjection

namespace OpenTelemetry.Metrics
{
   public static class OpenTelemetryDependencyInjectionMeterProviderBuilderExtensions
   {
-       public static MeterProviderBuilder ConfigureBuilder(this MeterProviderBuilder meterProviderBuilder, Action<IServiceProvider, MeterProviderBuilder> configure) {}
+       internal static MeterProviderBuilder ConfigureBuilder(this MeterProviderBuilder meterProviderBuilder, Action<IServiceProvider, MeterProviderBuilder> configure) {}

        // Added earlier in 1.4.0
        public static MeterProviderBuilder AddInstrumentation<T>(this MeterProviderBuilder meterProviderBuilder, Func<IServiceProvider, T> instrumentationFactory) where T : class {}
   }
}

namespace OpenTelemetry.Trace
{
   public static class OpenTelemetryDependencyInjectionTracerProviderBuilderExtensions
   {
-       public static TracerProviderBuilder ConfigureBuilder(this TracerProviderBuilder tracerProviderBuilder, Action<IServiceProvider, TracerProviderBuilder> configure) {}
+       internal static TracerProviderBuilder ConfigureBuilder(this TracerProviderBuilder tracerProviderBuilder, Action<IServiceProvider, TracerProviderBuilder> configure) {}

        // Added earlier in 1.4.0
        public static TracerProviderBuilder AddInstrumentation<T>(this TracerProviderBuilder tracerProviderBuilder, Func<IServiceProvider, T> instrumentationFactory) where T : class {}
   }

OpenTelemetry

namespace OpenTelemetry.Metrics
{
   public static class MeterProviderBuilderExtensions
   {
+        public static MeterProviderBuilder AddReader(this MeterProviderBuilder meterProviderBuilder, Func<IServiceProvider, MetricReader> implementationFactory) {}
   }
}

namespace OpenTelemetry.Trace
{
   public static class TracerProviderBuilderExtensions
   {
+        public static TracerProviderBuilder SetSampler(this TracerProviderBuilder tracerProviderBuilder, Func<IServiceProvider, Sampler> implementationFactory) {}
+        public static TracerProviderBuilder AddProcessor(this TracerProviderBuilder tracerProviderBuilder, Func<IServiceProvider, BaseProcessor<Activity>> implementationFactory) {}
   }
}

TODOs
