[FIR] Split primary constructor parameter scope into two different

In init block or property initializers,
for `val x` declared in primary constructor,
`x` reference is now resolved to property, not to parameter.
So we need two different scopes for primary constructor,
one for 'pure' parameters and another one for all parameters,
including val/var ones.
