Call all plugins onResolve instead of using only the first one

Currently only the first plugin onResolve result will be used, this means there is no way to override a previous plugin result

Calling all plugins allows you to override previous plugins

The issue identifies the plugin onResolve entry point but names no file or test. Locate the dispatch logic in the esbuild source, then verify that all plugins are called and that a later result can override an earlier one, with coverage for that ordering.
