fix: add a new zone MACRO_SUB_OPT_NAME

[bitaoz]

Summary Resolve https://github.com/sassoftware/vscode-sas-extension/issues/652, Add a new zone MACRO_SUB_OPT_NAME, which is similar to PROC_SUB_OPT_NAME, VIEW_OR_PGM_SUB_OPT_NAME. It's the subtype of SUB_OPT_NAME.

Testing Type "%macro test (test);" and "enter", Indentation works properly.

[Zhirong2022]

New a .sas file, type code '%macro test;' at line1 and type Enter to the next line, type code '%let num=1;', it will indent automatically.

[Zhirong2022]

Auto indent works improperly with '%mend;' Type code below

%macro reportit(reuest);
    %if %upcase(&request)=STAT %then
        %do;
            proc means;
                title "summary of all numric variables";
            run;
        %end;
    %else %if %upcase(&request)=PRINTIT %then
        %do;
            proc print;
                title "listing of data";
            run;
        %end;
    %else %put incorrect type;
    title;

Type Enter at the end of 'title;', try to type '%mend;'

[Zhirong2022]

Indentation has different behavior with 'set' statement

data popstate;
    set pf70 pm70 pf80 pm80;

data _null_;
    set sashelp.cars(drop=origin enginesize cylinders horsepower weight  wheelbase length);

[Zhirong2022]

Auto indent works improperly with typing %mend + macro name; Scenario1: If the macro code block nested with other code block.

%macro test;
  %let num=1;
  proc print data=sashelp.cars(obs=1);
  run;
  %mend test;

Scenario2: Different behavior between topic build and main build
