When searching for repository topics, either via the API, or via
Explore, paging did not work correctly, because it only applied when the
`page` parameter was non-zero. Paging should have applied when the page
size is greater than zero, which is what this patch does.
As a result, both the API, and the Explore endpoint will return paged
results (30 by default). As such, when managing topics on the frontend,
the offered completions will also be limited to a pageful of results,
based on what the user has already typed.
This drastically reduces the amount of traffic, and also the number of
the topics to choose from, and thus, the rendering time too.
The topics will be returned by popularity, with most used topics first.
A single page will contain `[api].DEFAULT_PAGING_NUM` (30 by default)
items that match the query. That's plenty to choose from.
Fixes#132.

- If a topic has zero repository count, it means that none of the
repositories are using that topic, that would make them 'useless' to
keep. One caveat is that if that topic is going to be used in the
future, it will be added again to the database, but simply with a new
ID.

The topics are saved in the `repo_topic` table.
They are also saved directly in the `repository` table.
Before this PR, only `AddTopic` and `SaveTopics` made sure the `topics`
field in the `repository` table was synced with the `repo_topic` table.
This PR makes sure `GenerateTopics` and `DeleteTopic`
also sync the `topics` in the repository table.
`RemoveTopicsFromRepo` doesn't need to sync the data
as it is only used to delete a repository.

Fix#19513
This PR introduce a new db method `InTransaction(context.Context)`,
and also builtin check on `db.TxContext` and `db.WithTx`.
There is also a new method `db.AutoTx` has been introduced but could be used by other PRs.
`WithTx` will always open a new transaction, if a transaction exist in context, return an error.
`AutoTx` will try to open a new transaction if no transaction exist in context.
That means it will always enter a transaction if there is no error.

A lot of our code is repeatedly testing if individual errors are
specific types of Not Exist errors. This is repetitative and unnecesary.
`Unwrap() error` provides a common way of labelling an error as a
NotExist error and we can/should use this.
This PR has chosen to use the common `io/fs` errors e.g.
`fs.ErrNotExist` for our errors. This is in some ways not completely
correct as these are not filesystem errors but it seems like a
reasonable thing to do and would allow us to simplify a lot of our code
to `errors.Is(err, fs.ErrNotExist)` instead of
`package.IsErr...NotExist(err)`
I am open to suggestions to use a different base error - perhaps
`models/db.ErrNotExist` if that would be felt to be better.
