perf: cache loaded plugins

[sxyazi]

Resolves #703.

This PR removes the global variable state and passes it as a parameter, sync plugin:

return {
-  entry = function()
+  entry = function(state)
    state.foo = 1;
  end
}

Also sync block:

- local get_hovered_url = ya.sync(function()
+ local get_hovered_url = ya.sync(function(state)
  state.foo = 1;
end)

This allows the plugin to access the state during initialization:

-- ~/.config/yazi/plugins/test.yazi/init.lua
return {
  setup = function(state, opts)
    state.my_opt1 = opts.opt1
  end
}

-- ~/.config/yazi/init.lua
require("test"):setup {
  opt1 = "value1"
}

Hey, I tested a bit and the issue that was introduced in #702 is fixed, and I'm also able to get access to the state variable as you described , however something seems wrong with state inside the entry function, I can't access variables defined from setup in entry, however if I call a ya.sync method in entry I can access that variable.

The issue can be seen in the following test plugin, the print inside entry returns nil, but all other prints have the correct value for state.opt.

local sync = ya.sync(function(state)
	print("SYNC: " .. tostring(state.opt))
end)

local sync2 = ya.sync(function(state)
	ya.err("SYNC2: " .. tostring(state.opt))
end)

return {
	entry = function(state)
		ya.err("ENTRY: " .. tostring(state.opt))

		sync2()
	end,
	setup = function(state)
		state.opt = "test"

		sync()
	end,
}

EDIT: Nevermind, that's how it works 😄, so yes, it's working correctly
