Use HINT_FROM_SOONG if ninja_log doesn't exist
In non-incremental build, there is no ninja_log. For this case, use
HINT_FROM_SOONG as an alternative solution.
Bug: 273947040
Test: 1.m after removing out/.ninja_log
2.check if non-incremental CI build uses HINT_FROM_SOOONG
3.check if incremental CI build uses NINJA_LOG
4.check if there is no regression in CUJ
