dont qualify literal_binds with literal_execute

dont qualify literal_binds with literal_execute

this appears to be unnecessary and prevents end-user
literal_binds case from working.

Fixed issue where the ``literal_binds`` compiler flag, as used externally
to render bound parameters inline, would fail to work when used with a
certain class of parameters known as "literal_execute", which covers things
like LIMIT and OFFSET values for dialects where the drivers don't allow a
bound parameter, such as SQL Server's "TOP" clause.  The issue locally
seemed to affect only the MSSQL dialect.

Fixes: #6863
