[V2] Upgrade pattern improvements

[thermiteplasma]

PR to match when variables are passed as the component name and also handle multi line arguments. Also added the missing $this->dispatch|$this->emit methods called from a PHP class

It should handle a period or hyphen in the component name and supports many argument formatting types

Below are some test regex examples

1. Using $dispatch: https://regexr.com/7iajb
2. Using $this->dispatch: https://regexr.com/7iafs
3. Using Livewire.dispatch: https://regexr.com/7iaje
