fix(core/acl): fix core:default schema generation (#10971)

* remove dbg! in resources test

* use methods from `fs` and `env` qualified

* share `ACL_MANIFESTS_FILE_NAME` and `CAPABILITIES_FILE_NAME` consts across crates

* simplifiy `Manifest::new` code for better readability

* move reading global api scripts logic next to the function that defines it

* [tauri-build] move acl logic from lib.rs to acl.rs

* use const value for schema instead of enum value with a single variant

* remove unnecessary info from permissions hover

* move related functions next to each other & improve readability of others

* use methods from `fs` and `env` qualified

* fix warning, unused return in test

* document some functions

* improve generated schema for better scope schema completion, simplify, reorganize and document the logic

previously if you had `fs` and `http` plugins added in a project
and then try to write an extended permission for `fs:allow-app-meta`
```json
{
      "identifier": "fs:allow-app-meta",
      "allow": [ <here> ]
}
```
and even though identifier is from `fs` plugin,
the JSON schema suggests `path` and `url`.
Now it will only suggest  relevant field which is `path`

* resolve permissions from other plugins, generate `core:default` as a normal set instead of special logic

* move `PERMISSION_SCHEMAS_FOLDER_NAME` to acl module

* use gneric trait because of MSRV

* ensure `gen/schemas` dir is created

* clippy
