fix: utilities exports

[lee-chase]

Contributes to #923

This is PR 1 of 2, which makes changes to the utilities package exports.

• Adds TypeScript Support to @carbon-labs/utilities
• packages/utilities/package.json - Added TypeScript exports, sideEffects: false for tree-shaking
• packages/utilities/scripts/build.sh - Script to copy .d.ts files during build
• Fix Rollup Resolution (packages/react/tasks/build.js)

What This Achieves

Makes @carbon-labs/utilities fully TypeScript-compatible. TypeScript projects can now import from this package with full type safety and IDE autocomplete. All existing JavaScript consumers continue to work unchanged.

Corrects the rollup resolution that was incorrectly using the selecting the src folder of @carbon-labs/utilities.

PR 2 will

1. Update usage of @carbon-labs/utilties

e.g.

// Before
import { usePrefix } from '@carbon-labs/utilities/es/index.js';

// After
import { usePrefix } from '@carbon-labs/utilities';

2. Update Dependencies from canary to latest and/or newes version number.

{
  "peerDependencies": {
    "@carbon-labs/utilities": "^0.17.0"
  }
}

Testing / Reviewing

The build still runs.

I know we've had fun with exports before so I thought I'd try and split this up into the change required to @carbon-labs/utilities which is preventing adoption of Typescript in the Carbon-react-router-template project.

The second PR will address the 121 direct imports of @carbon/labs/utilities/es/....
In addition it would need to update the 22 imports some of which use old versions.

This LGTM, would like to get one more set of eyes on it before merging. @annawen1 are you able to take a quick look?
