  [Clang][OpenACC] Fixed getExtValue Call on Invalid Gang Dim (#221502)

**Problem**
When an invalid 'gang dim' value is used in `CheckGangDimExpr`, the
function prints the value into the diagnostic message by calling
`getExtValue`. This function asserts on values that can't fit into a
signed integer.

**Solution**
`APSInt` has a `<<` operator anyway so just use that.


The fix causes the message to print with the following formatting: 
```
test.cpp:5:40: error: argument to 'gang' clause dimension must be 1, 2, or 3: evaluated to 18'446'744'073'709'551'574
    5 | #pragma acc routine(S::foo) gang(dim : S::foo())
      |                                        ^
1 warning and 1 error generated.
```
Fixes #221418
