[SLC] inherit SymbolPsiLiteral from PsiLiteralExpression

We should use PsiLiteralExpression instead of PsiLiteral as it
is used in the Java world. Effectively, `psiLiteral` property
already has this type (as `createPsiExpression` produce `PsiExpression`),
but we missed this part before and used just PsiLiteral for our
own class
