Merijn Hendriks 9c89c31c68 Modernize HTTP v2 (!104)
This PR won't affect modders who have already updated their mods to 3.8.0. They just need to re-compile.

This is a resubmission of my previous PR (SPT-AKI/Modules#99) with additional code cleanup and fixes.
Instead of outright removing the functionality, this time I deprecate it instead (marked for removal in next release).

Requires SPT-AKI/Server#274 to function.

## Overview

- HTTP modernization
  - Adds `Aki.Common.Http.Client`, a replacement for `Aki.Common.Http.Request` and builds on top of `System.Net.Http.HttpClient`
  - Implements failsafe retries when requesting during busy connections
  - Improved debugging
  - Improved performance
  - Deprecades old request code
- Bundle system
  - Fixes remote downloaded bundles using external IP
  - Implements functional bundle caching from remote sources
  - Implements multi-threaded bundle downloads
  - Implements Unity-compatible bundle format support
  - Extensive cleanup
  - Deprecated unneccecary models

## Why?

In it's current state, the bundle system is ducktaped together in 2021, fundumentally broken and in desperate need of a cleanup and fixes.
The HTTP code hasn't been updated since 2021, and `HttpWebRequest` has been deprecated by Microsoft for a while now.
There was also a lot of opportunity left for simple performance gains that even reduces the complexity of the code.

As for why not two separate PRs (HTTP modernization, bundle rework): both were deeply interconnected. A change in one requires modification in the other. Hence the current approach.

## Testing

The code has been validated and tested by @TheSparta and me.
A large section of the code has been implemented and tested extensively by modders.

### Local

1. Start the game from 127.0.0.1
2. The game starts loading bundles from the mods path

### Remote, full re-aquire

1. Start the server from LAN IP (http.json, set host to `cmd > ipconfig` address, example: `192.168.178.32`)
2. Start the game from LAN IP
3. A folder named `user/cache/bundles` is created

### Remote, partial-aquire (deleted)

1. Ensure all bundles are cached
2. Delete one of the aquired bundles from cache
3. Start the server from LAN IP (http.json, set host to `cmd > ipconfig` address, example: `192.168.178.32`)
4. Start the game from LAN IP
5. The bundle is redownloaded

### Remote, partial-aquire (invalid crc)

1. Ensure all bundles are cached
2. Update a bundle mod with a new bundle on the same path
3. Start the server from LAN IP (http.json, set host to `cmd > ipconfig` address, example: `192.168.178.32`)
4. Start the game from LAN IP
5. The bundle is redownloaded

### Remote, use cache

1. Ensure all bundles are cached
2. Start the server from LAN IP (http.json, set host to `cmd > ipconfig` address, example: `192.168.178.32`)
3. Start the game from LAN IP
4. The game starts loading bundles from the cache path

## Risk assessment

In order to reduce friction between releases, this PR introduces a deprecation system.
Obsolete classes and methods have been marked deprecated.
These will remain available for the current release and continue to function as normal for this release.
A warning will be displayed during build when a modder relies on the deprecated functionality.
The marked classes and methods are to be removed in the next release.

The server-side changes have no impact on modders.

## Deprecation

The following classes are affected:

- `Aki.Common.Http.Request`: Replaced by `Aki.Common.Http.Request`
- `Aki.Common.Http.WebConstants`: Replaced by functionality from `System.Net.Http`
- `Aki.Custom.Models.BundleInfo`: Replaced by `Aki.Custom.Models.BundleItem`

The following methods are affected:

- `Aki.Common.Http.RequestHandler.GetData(path, hasHost)`: `hasHost` enables connection outside intended host.
- `Aki.Common.Http.RequestHandler.GetJson(path, hasHost)`: `hasHost` enables connection outside intended host.
- `Aki.Common.Http.RequestHandler.PostJson(path, json, hasHost)`: `hasHost` enables connection outside intended host.
- `Aki.Common.Http.RequestHandler.PutJson(path, json, hasHost)`: `hasHost` enables connection outside intended host.

The deprecated methods and `Aki.Custom.Models.BundleInfo` are self-contained and can be removed independently.
The deprecated classes require removal of all deprecated code at once.
