feat: remove usage of build yaml (#4192)
# What does this PR do?

the build.yaml is only used in the following ways:

1. list-deps
2. distribution code-gen

since `llama stack build` no longer exists, I found myself asking "why
do we need two different files for list-deps and run"?

Removing the BuildConfig and altering the usage of the
DistributionTemplate in llama stack list-deps is the first step in
removing the build yaml entirely.

Removing the BuildConfig and build.yaml cuts the files users need to
maintain in half, and allows us to focus on the stability of _just_ the
run.yaml

This PR removes the build.yaml, BuildConfig datatype, and its usage
throughout the codebase. Users are now expected to point to run.yaml
files when running list-deps, and our codebase automatically uses these
types now for things like `get_provider_registry`.

**Additionally, two renames: `StackRunConfig` -> `StackConfig` and
`run.yaml` -> `config.yaml`.**

The build.yaml made sense for when we were managing the build process
for the user and actually _producing_ a run.yaml _from_ the build.yaml,
but now that we are simply just getting the provider registry and
listing the deps, switching to config.yaml simplifies the scope here
greatly.

## Test Plan

existing list-deps usage should work in the tests.

# Telemetry
The preferred way to instrument Llama Stack is with OpenTelemetry. Llama Stack enriches the data
collected by OpenTelemetry to capture helpful information about the performance and behavior of your
application. Here is an example of how to forward your telemetry to an OTLP collector from Llama Stack:
```sh
export OTEL_EXPORTER_OTLP_ENDPOINT="http://127.0.0.1:4318"
export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
export OTEL_SERVICE_NAME="llama-stack-server"
uv pip install opentelemetry-distro opentelemetry-exporter-otlp
uv run opentelemetry-bootstrap -a requirements | uv pip install --requirement -
uv run opentelemetry-instrument llama stack run config.yaml
```
### Known issues
Some database instrumentation libraries have a known bug where spans get wrapped twice, or do not get connected to a trace.
To prevent this, you can disable database specific tracing, and rely just on the SQLAlchemy tracing. If you are using
`sqlite3` as your database, for example, you can disable the additional tracing like this:
```sh
export OTEL_PYTHON_DISABLED_INSTRUMENTATIONS="sqlite3"
```
