fix(cli): wmic not found on modern Windows systems (aws#17070)

Apparently Microsoft stopped shipping `wmic.exe` in certain situations
(modern systems?). We rely on this to detect whether we are on an EC2
instance, so that we do or do not configure the IMDS credential
provider (we try to avoid the IMDS credential provider if unnecessary,
because in certain network setups it may hang for a long time failing to
connect to `169.254.169.254`).

If calling `wmic` fails, just assume we're not on an EC2 instance
and proceed.

Fixes aws#16419.
