[FIR] KT-54978 Prohibit explicit type arguments in property accesses

Browse Source 
- Add a checker which ensures that property accesses have no explicit
  type arguments. If an error on the property access's callee reference
  already exists, the new error is not reported in favor of the existing
  error, as the property access may have been intended to be a function
  call.
- `complicatedLTGT.fir.kt`: The underlying parser issue is not yet
  solved, which is why `x` is parsed as a property access with explicit
  type arguments.
- `reservedExpressionSyntax` tests: This new check makes a lot of the
  access expressions in these tests illegal, so valid lines have been
  added and invalid lines appropriately marked with
  `EXPLICIT_TYPE_ARGUMENTS_IN_PROPERTY_ACCESS` errors.
