Add file status for API "Get a single commit from a repository" () ()
 To obtain a closer behavior to the api from github, the status
(added, modified, removed) of a file should be available in addition to
the filename.
See github doc :

Filter get single commit ()
Pretty much the same thing as  but for getting a single commit
instead of getting a list of commits

Filters for GetAllCommits ()
The `GetAllCommits` endpoint can be pretty slow, especially in repos
with a lot of commits. The issue is that it spends a lot of time
calculating information that may not be useful/needed by the user.

The `stat` param was previously added in  to address this, by
allowing the user to disable the calculating stats for each commit. But
this has two issues:
1. The name `stat` is rather misleading, because disabling `stat`
disables the Stat **and** Files. This should be separated out into two
different params, because getting a list of affected files is much less
expensive than calculating the stats
2. There's still other costly information provided that the user may not
need, such as `Verification`

This PR, adds two parameters to the endpoint, `files` and `verification`
to allow the user to explicitly disable this information when listing
commits. The default behavior is true.

Add context cache as a request level cache ()
To avoid duplicated load of the same data in an HTTP request, we can set
a context cache to do that. i.e. Some pages may load a user from a
database with the same id in different areas on the same page. But the
code is hidden in two different deep logic. How should we share the
user? As a result of this PR, now if both entry functions accept
`context.Context` as the first parameter and we just need to refactor
`GetUserByID` to reuse the user from the context cache. Then it will not
be loaded twice on an HTTP request.

But of course, sometimes we would like to reload an object from the
database, that's why `RemoveContextData` is also exposed.

The core context cache is here. It defines a new context
```go
type cacheContext struct {
	ctx  context.Context
	data map[any]map[any]any
        lock sync.RWMutex
}

var cacheContextKey = struct{}{}

func WithCacheContext(ctx context.Context) context.Context {
	return context.WithValue(ctx, cacheContextKey, &cacheContext{
		ctx:  ctx,
		data: make(map[any]map[any]any),
	})
}
```

Then you can use the below 4 methods to read/write/del the data within
the same context.

```go
func GetContextData(ctx context.Context, tp, key any) any
func SetContextData(ctx context.Context, tp, key, value any)
func RemoveContextData(ctx context.Context, tp, key any)
func GetWithContextCache[T any](ctx context.Context, cacheGroupKey string, cacheTargetID any, f func() (T, error)) (T, error)
```

Then let's take a look at how `system.GetString` implement it.

```go
func GetSetting(ctx context.Context, key string) (string, error) {
	return cache.GetWithContextCache(ctx, contextCacheKey, key, func() (string, error) {
		return cache.GetString(genSettingCacheKey(key), func() (string, error) {
			res, err := GetSettingNoCache(ctx, key)
			if err != nil {
				return "", err
			}
			return res.SettingValue, nil
		})
	})
}
```

First, it will check if context data include the setting object with the
key. If not, it will query from the global cache which may be memory or
a Redis cache. If not, it will get the object from the database. In the
end, if the object gets from the global cache or database, it will be
set into the context cache.

An object stored in the context cache will only be destroyed after the
context disappeared.

Move convert package to services ()
Addition to 

The `convert` package relies heavily on different models which is
[disallowed by our definition of
modules](https://github.com/go-gitea/gitea/blob/main/CONTRIBUTING.md#design-guideline).
This helps to prevent possible import cycles.
