You can now run swift sdk configure --sdk-root-path /some/sdk/root sdk-id without needing to specify the target triple

Motivation:

The Android SDK (swiftlang/swift#80788 (comment)) needs to have its sdkRootPath configured to point to an external NDK sysroot. But it contains many different target triples, like armv7-unknown-linux-androideabi33 and x86_64-unknown-linux-android29, all of which need to be configured to point to the same sysroot. Following on to #8687 and swiftlang/swift-evolution#2888, this PR enables running a single command to configure the entire SDK, like so:

swift run swift-sdk configure --sdk-root-path ~/Library/Android/sdk/ndk/27.0.12077973/toolchains/llvm/prebuilt/darwin-x86_64/sysroot swift-6.1-RELEASE-android-24-0.1

This will result in configurations being created for each of the target triples for the SDK ID.

In addition, this fixes #8584, where swift sdk configure with a specified target triple didn't work at all, and instead would configure some random target triple for the specified SDK.

Modifications:

Make the targetTriple flag for ConfigureSwiftSDK optional and, when nil, apply the command to all triples included in the specified SDK.

Result:

Fixes #8584 and enables configuring multiple target triples with a single swift sdk configure command.

Seems good, I think the reviewers will ask for a test though. Running it through self-hosted CI to make sure the patch didn't break anything.
