Use abbreviation when returning arguments for a KSType

[yigit]

This PR fixes a problem in KSType where it was not returning the right type arguments for TypeAliases.

For input:

typealias MyList = MyList<Int>
val x: MyList = TODO()

Querying the typeArguments of x would return [Int] while also returning its declaration as MyList.
This makes it looks like MyList<Int><Int>.
To fix it, I updated KSType.arguments to use the abbreviation type instead of the KotlinType.
Also, updated the test to add more cases and make it print the arguments for each type. I refactored the
test a bit to print types of properties instead of all found types to make the output more readable (happy to revert that part).

Fixes: #881
Test: typeAlias.kt
