Add Func() suffix for Copy Invocation and Copy Call for Class Queries

[evshvarov]

Query element of a class now has two options: Show plan and Copy Invocation:

The Show Plan works pretty well and shows the query plan on the side.

Copy Invocation copies the classname and method into the buffer but it is not usable, as to call this query in ObjectScript a Func() suffix should be added every time.
myclass.List10Func() in this case.
Let's add it to the Copy Invocation for class queries?

In addition, could we add Copy Call entry too, which will copy into a clipboard an SQL construction t call this method. so in this case it will be:

CALL esh_lcrm.company_List10()

Hi @evshvarov, this is a vscode-objectscript issue so I will open a PR there. Adding the Func suffix will be easy. I'm not going to add a "Copy Call" though.
