[CK] Clean up Stream-K remnants in old CK and fix
 static_assert in CK Tile (#8595)

## Motivation

This PR is cleans up some Stream-K documentation (e.g., typos, unneeded
docs) and fixes an error in a Stream-K static assert. This PR adds no
new functionality.

## Technical Details
Exact details about the clean-up changes are as follows:
- Removes Stream-K documentation from old CK that were missed in PR
#8141.
- Fixes `static_assert` syntax in Stream-K kernel by adding `constexpr`
to if-else condition and correcting empty message parameter.
- Cleans up some typos in some Doxygen comments in the CK Tile Stream-K
kernel file.

## Test Plan

Ran existing tests locally; no new functionality was added, so no new
tests were added.

## Test Result

Tests passed.
