[aws-sdk-cpp] Fix linking issue when using MinGW (#39064)

It appears like the aws-sdk-cpp maintainers, in an attempt to avoid a
warning when compiling with Visual Studio, opted to use a Microsoft-only
function for reading environment variables. As a result, linking the
library will fail in MinGW environments. This PR adds a patch to
aws-sdk-cpp port that will replace the non-standard function with a
standard compliant version when being compiled for Windows using a
non-Microsoft compiler.

- [x] Changes comply with the [maintainer
guide](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/contributing/maintainer-guide.md).
- [ ] SHA512s are updated for each updated download.
- [ ] The "supports" clause reflects platforms that may be fixed by this
new version.
- [ ] Any fixed [CI
baseline](https://github.com/microsoft/vcpkg/blob/master/scripts/ci.baseline.txt)
entries are removed from that file.
- [ ] Any patches that are no longer applied are deleted from the port's
directory.
- [x] The version database is fixed by rerunning `./vcpkg x-add-version
--all` and committing the result.
- [x] Only one version is added to each modified port's versions file.
