Migrate @azure-rest/batch to import subpath design

[deyaaeldeen]

Description

Migrates the @azure-rest/batch package to the import subpath design pattern using #platform/* wildcard imports.

Changes

• Create config/ directory with tsconfigs extending from eng/tsconfigs/
• Update warp.config.yml to extend base and use local tsconfigs
• Remove polyfillSuffix in favor of #platform/* wildcard imports
• Update package.json imports field with browser/react-native mappings
• Update eslint.config.mjs with projectService: false
• Update vitest.browser.config.ts to use eng/vitestconfigs/browser.config.ts
• Delete old root tsconfig files

Benefits

• Enables proper type separation with no mixing of node/dom/RN types
• Warp now references tsconfigs under the config/ folder
• Consistent with other migrated packages (identity, storage-common, etc.)

Verification

• ✅ Build passes: pnpm turbo build --filter=@azure-rest/batch...
• ✅ TypeScript validation passes: tsc -b --noEmit
• ✅ Lint passes: npm run lint

This is going to be removed in favor of @azure/batch

Pull request overview

This PR migrates @azure-rest/batch to the import-subpath (#platform/*) design by moving TS configs under config/, updating Warp to use those configs, and aligning browser testing/linting setup with other migrated packages.

Changes:

• Switch Warp to extend the repo base config and point each target at config/tsconfig.*.json (dropping polyfillSuffix).
• Update package scripts/config to use config/ tsconfigs, add #platform/* condition mappings, and adjust Vitest browser config to use eng/vitestconfigs/browser.config.ts.
• Add new config/ tsconfigs (src/test/samples/snippets/lint) and remove the legacy root-level tsconfig files.
