Jonathan A. Sternberg 89db01ef97 cli: add otel sdk tracing and metric providers to the core cli
This adds the code used by buildx and compose into the default CLI
program to help normalize the usage of these APIs and allow code reuse
between projects. It also allows these projects to benefit from
improvements or changes that may be made by another team.

At the moment, these APIs are a pretty thin layer on the OTEL SDK. It
configures an additional exporter to a docker endpoint that's used for
usage collection and is only active if the option is configured in
docker desktop.

This also upgrades the OTEL version to v1.19 which is the one being used
by buildkit, buildx, compose, etc.
