Enhance gradle tasks for managing lockfiles (#3829)

## Description
This PR introduces and updates gradle tasks for managing lockfiles. Here
are the highlights:
- [The SDK
lockfile](https://github.com/smithy-lang/smithy-rs/blob/main/aws/sdk/Cargo.lock)
can now be generated directly within the `smithy-rs` repository without
the `aws-sdk-rust` repository.
- The SDK lockfile can be synchronized with runtime lockfiles, updating
only new dependencies while preserving the versions of existing ones.
- To prevent updating broken dependencies to the latest versions, we
track the last known good versions and downgrade them to those versions.

New/updated gradle tasks are intended for automation:
- This existing task no longer requires `-Paws-sdk-rust-path`. We plan
to incorporate it into a weekly GitHub Action to automate lockfile
updates:
```
./gradlew aws:sdk:cargoUpdateAllLockfiles
```
- This new task synchronizes the SDK lockfile with runtime lockfiles. We
plan to integrate it into pre-commit hooks:
```
./gradlew aws:sdk:syncAwsSdkLockfile  
```

In addition, this PR has updated the SDK lockfile by executing
`./gradlew aws:sdk:syncAwsSdkLockfile`. The updated lockfile no longer
includes many SDK crates that are unused in CI/CD processes. The new SDK
lockfile is in sync with the runtime lockfiles:
```
➜  smithy-rs git:(ysaito/enhance-gradle-tasks-for-lockfile) sdk-lockfiles audit
2024-09-12T16:02:25.193765Z  INFO sdk_lockfiles::audit: checking whether `rust-runtime/Cargo.lock` is covered by the SDK lockfile...
2024-09-12T16:02:25.224862Z  INFO sdk_lockfiles::audit: checking whether `aws/rust-runtime/Cargo.lock` is covered by the SDK lockfile...
2024-09-12T16:02:25.225389Z  INFO sdk_lockfiles::audit: checking whether `aws/rust-runtime/aws-config/Cargo.lock` is covered by the SDK lockfile...
SUCCESS
```

## Testing
I have verified the change against basic use cases:

#### When running `cargoUpdateAllLockfiles`, dependencies will be
updated to their latest versions, while broken crates will be pinned to
the last known good versions.

When we execute  
```
smithy-rs git:(ysaito/enhance-gradle-tasks-for-lockfile) ✗ ./gradlew aws:sdk:cargoUpdateAllLockfiles
...
BUILD SUCCESSFUL in 1m 7s
```
all lockfiles include the latest versions of dependencies, except for
those that are pinned due to being broken. Currently, minicbor is
[pinned to
0.24.2](https://github.com/smithy-lang/smithy-rs/blob/7f1d992214c25347fffeea63f8ceb58f77c7a8bb/aws/sdk/build.gradle.kts#L503-L504):
```

```

```
Finally, the `sdk-lockfiles audit` command should run successfully after
updating all lockfiles:
```
➜  smithy-rs git:(ysaito/enhance-gradle-tasks-for-lockfile) ✗ sdk-lockfiles audit                       
2024-09-12T15:35:47.890530Z  INFO sdk_lockfiles::audit: checking whether `rust-runtime/Cargo.lock` is covered by the SDK lockfile...

2024-09-12T15:35:47.922898Z  INFO sdk_lockfiles::audit: checking whether `aws/rust-runtime/aws-config/Cargo.lock` is covered by the SDK lockfile...
SUCCESS
```

I also specified multiple broken dependencies and verified they were all
downgraded to the specified versions.

#### When a new dependency is added to a runtime crate, running
`syncAwsSdkLockfile` will ensure that this new dependency is included in
the SDK lockfile.

For instance, with [this hypothetical new
dependency](https://github.com/smithy-lang/smithy-rs/pull/3826/files#diff-1ff3734bb74b7c43e3bd74b410f7058c6d40dbe9380458f642201035f9217457):

`jiff` (0.1.13), used by `rust-runtime/Cargo.lock`, is not contained in SDK lockfile!
Error: there are lockfile audit failures
```
If we then execute  
```
smithy-rs git:(ysaito/enhance-gradle-tasks-for-lockfile) ✗ ./gradlew aws:sdk:syncAwsSdkLockfile
...
BUILD SUCCESSFUL in 1m 17s
```
the SDK lockfile will be updated to reflect only the change from
`rust-runtime/Cargo.lock`:
