feat(es/minifier): Ignore more expressions in sequential inliner (#5961)

feat(es/minifier): Inline lazily initialized variables (#5737)
Safety:

For a function-local variable, an expression with side-effects would be a call, including an indirect one with a member expression.

 - If the call is function-local, it will be analyzed by the analyzer and inliner will not work.
 - If the call is not a function-local one, it cannot modify the local variable.
