Fix incorrect deduplication of otelcol_exporter_queue_size and
otelcol_exporter_queue_capacity metrics if multiple exporters are used.

The registered callbacks are ignored for now, which is the same behavior
as before. Ideally, we would need to unregister them properly.
This will be used in a follow up PR that allows initialization of
optional internal metrics which address the queue metric use-case.

Fixing this bug required a change in mdatagen to ensure attributes could
be passed in to the telemetry builder.

This allows components to set the minimum level needed for them to
produce telemetry. By default, this is set to
`configtelemetryLevelBasic`. If the telemetry level is below that
minimum level, then the noop meter is used for metrics.

This PR adds the ability to configure asynchronous (observable)
instruments via mdatagen. This requires providing a mechanism to set
options to pass in the callbacks that will be called at the time of the
observation.

#### Description
This updates mdatagen to generate internal telemetry for components
based on metadata.yaml configuration.
#### Testing
Added tests to mdatagen and updated the batch processor to use this as
well for synchronous counters and histogram

**Description:**
- Adds `component.MustNewType` to create a type. This function panics if
the type has invalid characters. Add similar functions
`component.MustNewID` and `component.MustNewIDWithName`.
- Adds `component.Type.String` to recover the string
- Use `component.MustNewType`, `component.MustNewID`,
`component.MustNewIDWithName` and `component.Type.String` everywhere in
this codebase. To do this I changed `component.Type` into an opaque
struct and checked for compile-time errors.
Some notes:
1. All components currently on core and contrib follow this rule. This
is still breaking for other components.
2. A future PR will change this into a struct, to actually validate this
(right now you can just do `component.Type("anything")` to bypass
validation). I want to do this in two steps to avoid breaking contrib
tests: we first introduce this function, and after that we change into a
struct.
