which only extends from tsconfig.json. There might be more customization for
packages in the early days but not any more.
This PR removes it and updates packages to extends tsconfig.json directly

### Describe the problem that is addressed by this PR
This PR is to create a new package `@azure/eventgrid-namespaces`. This
new package is associated with the existing package `@azure/eventgrid`.
Earlier, we has a beta version of the `@azure/eventgrid` package and the
source code for this beta version is available in the
[`feature/eventgrid/4_13_beta_1`](https://github.com/Azure/azure-sdk-for-js/tree/feature/eventgrid/4_13_beta_1).
In this beta version, in addition to the regular
`EventGridPublisherClient`, we also have a new
[`EventGridClient`](https://github.com/Azure/azure-sdk-for-js/blob/feature/eventgrid/4_13_beta_1/sdk/eventgrid/eventgrid/src/eventGridClientV2.ts).
With this PR, we are extracting this client alone into its own new
package.
