…andler.destroy() (#4400)

Fixes #3922

### Description
Adds the high-level Request and Response interfaces

### Testing
`yarn test:all`

### Description
Adds `Field`, `FieldPosition`, and `Fields` types to `protocol-http`.

### Testing
`yarn test:all`

### Description
Merges implementations of util-stream-browser and util-stream-node into a single package, util-stream.
The implementations were left unchanged, but some adjustments were made to the `package.json` to
accommodate both implementations, and in the jest config to test the browser implementation.

### Testing
- In `packages/util-stream`: `yarn test`
- In `clients/client-s3`: 
  - Updated dependencies to only use `util-stream`
  - Updated runtime config to use `util-stream`
  - `yarn ts-mocha test/flexibleChecksums.spec.ts`
- Using the [aws-sdk-js-tests repo](https://github.com/aws-samples/aws-sdk-js-tests), tested the [GetObject command](https://github.com/aws/aws-sdk-js-v3/blob/main/clients/client-s3/src/commands/GetObjectCommand.ts):
  - Configured a bucket and object to get, added S3 client, and set up client to run the command
  - Imported the local util-stream package from the aws-sdk-js-v3 directory
  - Modified the client's `config` object to use the `util-stream` implementations of `getAwsChunkedEncodingStream` and `sdk-stream-mixin`
  - Ran `yarn start:node` and `yarn start:web` to see S3 object returned properly

### Additional context
The `util-stream` package was not added to any clients or middleware. This will be done in subsequent commits.

* feat(util-stream): merge node and browser implementations

* chore(github): add codeowners for util-stream

* fix(util-stream): fix file names for node

The initial merging of the two packages resulted in a
mistake where the node and browser implementations of
sdk-stream-mixins did not have the same file names. This
caused both implementations to be loaded by the browser,
which would throw an error because the node implementation
uses the 'stream' package.

* fix(util-stream): update jest config to test browser implementation

* fix(util-stream): fix file names for browser/react-native

Fixes a mistake from initial merging of implementations where the
output files for browser and react-native were named incorrectly in
package.json.
