Bug fix to address performance issues when deserializing large payloads in `JsonObject` extension data.

Mitigates performance issues by optimizing the deserialization process for large `JsonObject` extension data properties.
- Added `LargeJsonObjectExtensionDataSerializationState` class in `System.Text.Json.Serialization.Converters` to handle large payloads efficiently.
- Updated `JsonObjectConverter` to use the new state class for large objects.
- Modified `ObjectDefaultConverter`, `ObjectWithParameterizedConstructorConverter`, and `ReadStackFrame` to complete deserialization using the new state class.
- Added tests in `JsonObjectTests` to validate the performance improvements with large payloads.

This improves the performance of removing extra fields in the ZipArchive by optimizing the removal process.

`src/libraries/System.IO.Compression/src/System/IO/Compression/ZipBlocks.cs`: Replaced multiple iterations and list operations with a single `RemoveAll` call to enhance efficiency.

This ports a fix for the `GetParts` method to improve part URI handling and collision detection.

`src/libraries/System.IO.Packaging/src/System/IO/Packaging/Package.cs`: Added sorting of parts array to ensure proper order, introduced a dictionary and list to track parts and detect collisions, and implemented a new method `CopyPartDictionaryToPartList` to copy parts to `_partList`.

…l TFMs

Note that Microsoft.Extensions.Caching.Memory is deployed OOB via NuGet, and multi-targets including support for netfx and ns2.0

Marvin is the string hashing used in modern .NET (https://github.com/dotnet/runtime/blob/main/src/libraries/System.Private.CoreLib/src/System/Marvin.cs); this change extends this behaviour to `string` keys when used with `MemoryCache` - noting that in many scenarios we *expect* the key to be a `string` (even though other types are allowed)

To do this we:

- ~~add a custom key equality comparer for use with `ConcurrentDictionary<object, CacheEntry>` (we do this on all TFMs, replacing the need for the dynamic lookup via `EqualityComparer<TKey>.Default`)~~
- split the internal dictionary into 2 - one for `string`, one for everything else
- in down-level TFMs only, provide a custom `string` key comparer with `MarvinHash` enabled (local snapshot since not available)

This gives us Marvin everywhere, and Marvin+rehash on netcore TFMs (rehash requires `TKey` === `string`)
