hostvariable support for exec sql block

[ap891843]

Description

Following program has multiple issue

Issues:

• Hover and go to definition doesn't work for SET A_B_C = :QWE.D-E-F
• commenting out variable definition for QWE, shows diagnostics at wrong location

       EXEC SQL
        UPDATE QWE_STATUS
            SET A_B_C  = :QWE.D-E-F
            WHERE TKN_UNIQUE_REFERENCE = :ASD.O-P-R
       END-EXEC  
           STOP RUN.

Expected behavior

• Hover and go to definition should work for host variables used in exec blocks
• Diagnostics should be located at the error source
