Consider adding esbuild's build function to plugin setup callback

[jed]

I recently created this plugin to eagerly evaluate a module. It requires access to esbuild's underlying build function, and instead of making plugin consumers pass it in, I'd love esbuild to provide it in the setup callback.

ie, instead of requiring users to do this:

await build({
   entryPoints: ['app.js'],
   plugins: [myPlugin(build)]
})

I could have them do this:

await build({
   entryPoints: ['app.js'],
   plugins: [myPlugin]
})

Just import esbuild by yourself:

import esbuild from 'esbuild'
esbuild.build()

I believe consumers have to ensure this code run in their environment (through import-maps or whatever), since esbuild itself is a normal es module.

i don't know what version the consumer of the plugin is running, and don't want to import two versions of esbuild (i'm not using npm).
