[APM] Optimize idx calls to native optional chaining (#34841)
* [APM] Add new kibana package '@kbn/babel-plugin-apm-idx' based on
'babel-plugin-idx' to work with the APM implementation of the deep
object property helper function. Configure it as a babel plugin in the
common babel preset.

* [APM] modified the expanded output code to handle null checking correction for nested properties and added tests.

* [APM] use same versions of babel and jest as core kibana. fixes broken tests.

* [APM] created namespaced package `@kbn/elastic-idx`. Made available the
apm/common/idx and the corresponding babel plugin under this package.
Modified all imports of apm/common/idx to @kbn/elastic-idx.

* [APM] add typescript build to the @kbn/elastic-idx package

* [APM] fix idx import and linting failures

* [APM] make @kbn/elastic-idx/babel plugin detect idx calls as member functions from the bound scope
