[SDK] Support independent programmatic configuration

[dbarker]

Fixes #4134 and follow up from ##3655 (review)

Break out the programmatic configuration to its own library so it can be used without the ryml dependency.

[edit - crossed out items that were broken out to separate PRs]

Changes

• Creates the programmatic configuration target (configuration_core)
• Adds configuration_core to the CMake install tests
• Adds deprecated names to components and deprecates the *builder components since they only depend on the SDK now and do not bring in dependencies.
• Adds programmatic_configuration_test.cc
• Fix issues found with the new test
  • LoggerConfigurator supporting min severity and trace based fields
  • Initialize members of config classes to the spec default constants.
  • Set the default parent based root sampler to always_on
  • Set the default sampler to parent based always on
  • Set all batch processor options that the user configured
  • Handle default metric stream aggregation
• Fix the cppcoreguidelines-pro-type-member-init warnings in configuration and sdk files used by the tests.
• Update INSTALL doc for the configuration targets
