[CK][CK_TILE] Fix CTest parsing to handle all test number
 formats (#5880)

## Motivation
Fix a bug in the smart-build --ctest-only filter that was incorrectly
excluding tests with numbers less than 100.

## Technical Details
The issue was caused by CTest formatting test numbers with variable
spacing based on the number of digits:
  - "Test   `#1`: name (3 spaces for tests 1-9)"
  - "Test  `#79`: name (2 spaces for tests 10-99)"
  - "Test `#100`: name (1 space for tests 100+)"

The previous code used `line.strip().startswith("Test #")` which only
matched tests with a single space (i.e., test numbers >= 100).

This caused tests like ck_tile_unit_sequence (Test #79) to be excluded
from smart-build test selection, resulting in CTest failures when the
binary wasn't built.

Solution: Replace string matching with a regex pattern that handles
all spacing variations: r'^\s*Test\s+#\d+:\s*(.+)$'

## Test Plan
Tested with test numbers from 1 to 12345.

## Test Result
  - Before: 48 tests selected (only tests #100+)
  - After: 146 tests selected (all CTest-registered tests)
