Add specs for File.match? from fast-glob (#15604)

Imports test cases for `File.match?` from https://github.com/oxc-project/fast-glob/blob/main/tests/test.rs to enhance the spec suite.

I'm planning to fix issue #15319 by porting the matching algorithm from `fast-glob` to Crystal. This is a preparatory step to import the test cases from the base implementation. Our current `match_spec.cr` lacks unit tests for many edge cases, which are covered here. Importing them beforehand makes it clear to identify the differences in behaviour, and it's easier to review in smaller bites.
I figure it should be easier to maintain this as a separate test file with a generator to easily include new test from upstream.
Most of the examples originate from other projects, bash and minimatch.
In violation of the DO NOT EDIT directive, I'm encoding the currently broken test cases directly in the generated file. This will be fixed shortly anyway.

The original tests also include a list of more complex patterns, which are tested against a huge list of paths. I'm skipping them here because they need specific code to run them, and add them separately. They're all broken anyway due to #15319.
Similarly, some fuzz specs are also a bit more complex for a simple transform, so they'll be added separately as well.
