The idea is to use a Layered Asset File-system (modules/assetfs/layered.go)
For example: when there are 2 layers: "custom", "builtin", when access
to asset "my/page.tmpl", the Layered Asset File-system will first try to
use "custom" assets, if not found, then use "builtin" assets.
This approach will hugely simplify a lot of code, make them testable.
Other changes:
* Simplify the AssetsHandlerFunc code
* Simplify the `gitea embedded` sub-command code

Close#24002
Two problems before:
1. The `log.Fatal` is missing after these `wrapFatal` calls, so the
error is not shown to users.
2. `GetTemplateAssetNames` has different behaviors for local files and
builtin assets, for builtin assets, it also returns directories, so we
need to check the extension again.
I have tested with `TAGS="bindata sqlite sqlite_unlock_notify" make
build && ./gitea` , it works well now. Before, the server responds
internal server error (because it doesn't complete the template parsing)
None of the features of `unrolled/render` package is used.
The Golang builtin "html/template" just works well. Then we can improve
our HTML render to resolve the "$.root.locale.Tr" problem as much as
possible.
Next step: we can have a template render pool (by Clone), then we can
inject global functions with dynamic context to every `Execute` calls.
Then we can use `{{Locale.Tr ....}}` directly in all templates , no need
to pass the `$.root.locale` again and again.
There are multiple duplicate reports of errors during template rendering
due to broken custom templates.
Unfortunately the error returned here is somewhat difficult for users to
understand and it doesn't return the context of the error.
This PR attempts to parse the error returned by the template renderer to
add in some further context including the filename of the template AND
the preceding lines within that template file.

A drawback is the previous generated template has been cached, so you
cannot get error in the UI but only from log

There are repeated issues reported whereby users are unable to interpret
the template errors. This PR adds some (somewhat complex) error handling
to the panic recovery for template renderering but hopefully makes the
interpretation of the error easier.

The recovery, API, Web and package frameworks all create their own HTML
Renderers. This increases the memory requirements of Gitea
unnecessarily with duplicate templates being kept in memory.
Further the reloading framework in dev mode for these involves locking
and recompiling all of the templates on each load. This will potentially
hide concurrency issues and it is inefficient.
This PR stores the templates renderer in the context and stores this
context in the NormalRoutes, it then creates a fsnotify.Watcher
framework to watch files.
The watching framework is then extended to the mailer templates which
were previously not being reloaded in dev.
Then the locales are simplified to a similar structure.
