Daniel ImmsandCursor 5d8da19c44 Keep path mappings for addons after core migration
Follow-up to https://github.com/xtermjs/xterm.js/issues/5896 / PR #5966.

Converting addons to ../../../src/common relative imports broke unit tests:
esbuild emits addon code under addons/*/out-esbuild/ without mirroring the
shared tree, so Node could not load TypeScript sources at runtime
(Cannot find module '../../../src/common/Lifecycle').

Core src/, test/, and headless continue to use relative imports with no
common/* path mappings. Addons keep the prior model until build layout
can share out-esbuild the same way as the main package.

Changes:
- Restore common/* and browser/* paths in addon src/test/benchmark tsconfigs
- Revert addon imports to common/ and browser/ path-mapped specifiers
- Restore NODE_PATH=out-esbuild in bin/test_unit.js for Mocha resolution
- Restore webpack resolve.alias on addons that bundle against out/

Fixes CI test-unit failures on remove-path-mappings-5896.
