ringabout a4a482b5ef fixes #25620; typekey skips incorrectly the base type of seqs etc. types for nim ic (#25621)
fixes #25620

This pull request includes a fix to the type key generation logic in the
compiler and updates to a test file to cover additional language
features. The most important changes are summarized below:

### Compiler logic fix

* In `compiler/typekeys.nim`, the `typeKey` procedure was updated to
iterate over all elements in `t.sonsImpl` starting from index 0 instead
of 1, ensuring that all type sons are considered during type key
generation.

### Test suite improvements

* The test file `tests/ic/tenum.nim` was renamed to
`tests/ic/tmiscs.nim`, and its output expectations were updated to
reflect the new test cases.
* Added new test cases to `tests/ic/tmiscs.nim` to cover sink and move
semantics, including the definition of a `BigObj` type and a `consume`
procedure that demonstrates moving and consuming large objects.

```nim
# Sink and move semantics
type
  BigObj = object
    data: seq[int]

proc consume(x: sink BigObj) =
  echo x.data.len

var b = BigObj(data: @[1, 2, 3, 4, 5])
consume(move b)
```

gives

```
