[WIP] Specialize `chklapackerror` to improve error messages (#51645)
 
This is an attempt at resolving
https://github.com/JuliaLang/julia/issues/46636. Since each LAPACK
function generally has a specific meaning attached to a positive error
code, this PR tries to specialize `chklapackerror` for the caller to
throw a more informative error instead of a `LAPACKException`. For
example:
```julia
julia> U = UpperTriangular([1 2; 0 0])
2×2 UpperTriangular{Int64, Matrix{Int64}}:
 1  2
 ⋅  0

julia> inv(U)
ERROR: SingularException(2)
[...]
```
Currently, I've only specialized it for `trtrs!`, but if this seems
reasonable, I'll add others.
