test: Speed up suite by prebundling barrel imports (#77)

Every test file that renders the grid paid ~7s loading modules. All
source files import from the igniteui-webcomponents barrel, which
re-exports the full component library. Rollup tree-shakes this in the
build, but web-test-runner serves unbundled ESM, so the browser fetched
249 modules per test page - banner, card, carousel and i18n-core
included, none of which the grid uses.

Prebundle the barrel with esbuild, tree-shaken to the 8 runtime symbols
src/ imports, and resolve the bare specifier to it. lit stays external
so no second copy of the runtime enters the graph. The export list is
derived by scanning src/ so it cannot drift.

Suite drops from 40.8s to 11.0s.
