Add glob file type support (#8006)

* Replace FileType::Suffix with FileType::Glob

Suffix is rather limited and cannot be used to match files which have
semantic meaning based on location + file type (for example, Github
Action workflow files). This patch adds support for a Glob FileType to
replace Suffix, which encompasses the existing behavior & adds
additional file matching functionality.

Globs are standard Unix-style path globs, which are matched against the
absolute path of the file. If the configured glob for a language is a
relative glob (that is, it isn't an absolute path or already starts with
a glob pattern), a glob pattern will be prepended to allow matching
relative paths from any directory.

The order of file type matching is also updated to first match on globs
and then on extension. This is necessary as most cases where
glob-matching is useful will have already been matched by an extension
if glob matching is done last.

* Convert file-types suffixes to globs

* Use globs for filename matching

Trying to match the file-type raw strings against both filename and
extension leads to files with the same name as the extension having the
incorrect syntax.

* Match dockerfiles with suffixes

It's common practice to add a suffix to dockerfiles based on their
context, e.g. `Dockerfile.dev`, `Dockerfile.prod`, etc.

* Make env filetype matching more generic

Match on `.env` or any `.env.*` files.

* Update docs

* Use GlobSet to match all file type globs at once

* Update todo.txt glob patterns

* Consolidate language Configuration and Loader creation

This is a refactor that improves the error handling for creating
the `helix_core::syntax::Loader` from the default and user language
configuration.

* Fix integration tests

* Add additional starlark file-type glob

@@ -78,24 +78,26 @@ from the above section. `file-types` is a list of strings or tables, for
 example:
 
 ```toml
-file-types = ["Makefile", "toml", { suffix = ".git/config" }]
+file-types = ["toml", { glob = "Makefile" }, { glob = ".git/config" }, { glob = ".github/workflows/*.yaml" } ]
 ```
 
 When determining a language configuration to use, Helix searches the file-types
 with the following priorities:
 
-1. Exact match: if the filename of a file is an exact match of a string in a
-   `file-types` list, that language wins. In the example above, `"Makefile"`
-   will match against `Makefile` files.
-2. Extension: if there are no exact matches, any `file-types` string that
-   matches the file extension of a given file wins. In the example above, the
-   `"toml"` matches files like `Cargo.toml` or `languages.toml`.
-3. Suffix: if there are still no matches, any values in `suffix` tables
-   are checked against the full path of the given file. In the example above,
-   the `{ suffix = ".git/config" }` would match against any `config` files
-   in `.git` directories. Note: `/` is used as the directory separator but is
-   replaced at runtime with the appropriate path separator for the operating
-   system, so this rule would match against `.git\config` files on Windows.
+1. Glob: values in `glob` tables are checked against the full path of the given
+   file. Globs are standard Unix-style path globs (e.g. the kind you use in Shell)
+   and can be used to match paths for a specific prefix, suffix, directory, etc.
+   In the above example, the `{ glob = "Makefile" }` config would match files
+   with the name `Makefile`, the `{ glob = ".git/config" }` config would match
+   `config` files in `.git` directories, and the `{ glob = ".github/workflows/*.yaml" }`
+   config would match any `yaml` files in `.github/workflow` directories. Note
+   that globs should always use the Unix path separator `/` even on Windows systems;
+   the matcher will automatically take the machine-specific separators into account.
+   If the glob isn't an absolute path or doesn't already start with a glob prefix,
+   `*/` will automatically be added to ensure it matches for any subdirectory.
+2. Extension: if there are no glob matches, any `file-types` string that matches
+   the file extension of a given file wins. In the example above, the `"toml"`
+   config matches files like `Cargo.toml` or `languages.toml`.
