Migrate vis_type_table plugin to synchronous lifecycle

[pgayvallet]

Required for #53268

In #89562, we migrated almost all plugins to synchronous lifecycle.

However, the vis_type_table plugin could not be migrated, because of the conditional lazy import the it is performing

kibana/src/plugins/vis_type_table/public/plugin.ts

Lines 44 to 57 in 3b3327d

	public async setup(
	core: CoreSetup<TablePluginStartDependencies>,
	deps: TablePluginSetupDependencies
	) {
	const { legacyVisEnabled } = this.initializerContext.config.get();
	if (legacyVisEnabled) {
	const { registerLegacyVis } = await import('./legacy');
	registerLegacyVis(core, deps, this.initializerContext);
	} else {
	const { registerTableVis } = await import('./register_vis');
	registerTableVis(core, deps, this.initializerContext);
	}
	}

Note that those config-based conditional imports seems to make sense, as they reduce the initial-load bundle size. However, this is not something that is going to work with synchronous plugins, nor a use-case we really thought about.

I'm unsure what should be done here to be honest:

1. Remove these lazy import and just load everything in the initial bundle by using 'plain' imports

Seems the most pragmatic, but OTOH it just doesn't feel right.

2. Keep the lazy import but remove the awaits and have the registerXXXVis performing the registration asynchronously.

Seems like an even worse option

3. ???

WDYT all?

@pgayvallet I just saw this! Thanx for reporting it. Right now this visualization has two implementations, the legacy one and the default one (which uses Eui datagrid). We plan to remove the legacy one on the next minors (before 7.15). When the old implementation will be removed this conditional lazy import will be removed too. Do you think we can wait for some minors? Or is it crucial from your side?

It would be totally fine to wait
