Tyler Yahn a64b9ec518 Fix package documentation name and return error in semconv/v1.36.0 (#7656) 
Identified in the review of #7648

Tyler Yahn 0b47699705 Add AddSet and RecordSet methods to semconv generated packages (#7223) 
The current design of the packages is for ergonomics, and it works well
at this. However, it is not the most performant. When a user passes a
slice of attributes it will use
[`metric.WithAttributes`](https://github.com/open-telemetry/opentelemetry-go/blob/cf787f3e3ad0093985b0834eaf63ceb679705545/metric/instrument.go#L372-L376):

```go
func WithAttributes(attributes ...attribute.KeyValue) MeasurementOption {
	cp := make([]attribute.KeyValue, len(attributes))
	copy(cp, attributes)
	return attrOpt{set: attribute.NewSet(cp...)}
}
```

This will copy the passed attributes and then pass that copy to
`attribute.NewSet` which adds its own allocation.

If a user is performance conscious and already have a set, allow them to
pass it directly and reduce the required allocations for the measurement
call.

## Alternatives Considered

### Why not allow users to just use `Inst()` method?

With the current design a user can still just call:

```go
counter.Inst().Add(ctx, val, metric.WithAttributeSet(set))
```

However, the option slice (in this case `[]metric.AddOption`) is
allocated on the call. Meaning a user will also need to recreate the
pooling that our semconv generated packages already handle.

Providing the `*Set` methods is convenient, but it also helps the
application performance as one larger pool will be less strain on the GC
than many smaller ones.

### Why not just call `WithAttributeSet` in the existing methods?

Instead of appending a `WithAttributes` option internal to all the
measurement methods, we could also just create a `Set` and pass that
with `WithAttributeSet`. This will avoid the additional slice copy that
`WithAttributes` does on top of calling `attribute.NewSet`.

However, this copy that `WithAttributes` does is important as calling
`attribute.NewSet` will sort the original slice. Bypassing that will
mean all the passed attribute slices will be modified when used.

This is not great as it is likely going to be unexpected behavior by the
user, and is the reason we copy the slice in `WithAttributes` in the
first place.

### Why not just copy user attributes to an amortized slice pool to
create a new `attribute.Set`?

The additional creation of an `[]attribute.KeyValue` that user
attributes are copied to in order to prevent modification can be
amortized with a pool. For example, #7249. There shouldn't be any
difference than between calling a `*Set` method introduced here vs the
non-`Set` method.

This is true, and motivates this type of change. However, also providing
these additional methods allows the user additional performance gains if
the set is used for more than one measurement. For example:

```go
set := attributes.NewSet(attrs)
counter1.AddSet(ctx, 1, set)
counter2.AddSet(ctx, 2, set)  // No additional set is created here.
```

Without these methods:

```go
counter1.Add(ctx, 1, attrs...) // A set is created for attrs
counter2.Add(ctx, 2, attrs...) // Another set is created for attrs
```

Each `attribute.Set` created will require an allocation (i.e. the
internal `any` field needs to be allocated to the heap). Meaning without
these methods a user will still not be able to write the most performant
code.

The attribute pool approach has merit, and should be pursued. However,
it does not invalidate the value of these changes.

Tyler Yahn 5e212ba8c6 Generate semconv/v1.36.0 (#7032) 
Resolve #7030 

This generation fixes the following:

- The `semconv/weaver.yaml` file is moved to the
`semconv/templates/registry/go` to [fix the
generation](https://github.com/open-telemetry/opentelemetry-go/issues/7030#issuecomment-3074916061).
- Deprecated enum `var`s are no longer generate.
- The deprecation of the previous `OSTypeZOS` (`z_os`) conflicts with
the replacement (`zos`).
- This matches all other generations where deprecated types are not
generated and the migration docs identify users need to upgrade when
upgrading packages.
- Fix metric description rendering to handle multi-line metric
descriptions.
- Fix filter of deprecated metrics in weaver configuration (see
https://github.com/open-telemetry/weaver/issues/847).

The release notes for v1.35.0 are included as we do not plan to add a
package for that release and it includes breaking changes being released
here (i.e. `az.namespace` and `az.service_request_id`)
