Remove markdown injection again
I really tried to make this work, but this stuff is so underdocumented and basically none of the regex options worked for me (not `match`, nor using `begin` and `end` pairs), VSCode basically doesn't help you out at all as it doesn't ever seem to report errors even when debugging an extension, so at this point I'm inclined to just remove this again, as it is only causing issues.

internal: Add run-tests command
This command is similar to `cargo test` except that it uses r-a to run tests instead of compiling and running them with rustc. This is slower than `cargo test` and it is only useful for me to see a bird view of what needs to be fixed. The current output is:
```
48 passed, 5028 failed, 2 ignored
All tests 174.74s, 648ginstr
```
48 is very low, but higher than what I originally thought.
Now that there is some passing tests, I can show the plan:

That is, at the end, I want to be able to immediately re run every test after every change. (0.5s is not really immediate, but it's not finished yet, and it is way better than 8s that running a typical test in r-a will take on my system)
Change comparsion for checking if number is negative to include 128
The last byte in Little-Endian representation of negative integers start at 128 (Ox80) till 255 (OxFF). The comparison before the fix didn't check for 128 which made is_negative variable as false.
Potentially fixes#15096
Added a test near positive extermes and two test near negative
extermes as well one for 0.
Added a test using the `as` cast and one with comparison with 0.
feature : assist delegate impl
This PR ( fixes#14386 ) introduces a new IDE assist that generates a trait impl for a struct that delegates a field. This is a draft because the current `ide_db::path_transform::PathTransform` produces some unwanted results when it deals with extern crates, an example of which I attach as a GIF.
GIFs :
1. A general case
2. A case where `ide_db::path_transform::PathTransform` fails to correctly resolve a property ( take `Allocator` as an example ) to its full path, thus causing an error to occur. ( Not to even mention that resolving this causes another error `use of unstable library feature 'allocator_api'` to occur
Reason: The last byte in Little Endian representation of negative
integers start at 128 (Ox80) till 255 (OxFF). The comparison before
the fix didn't check for 128 which made is_negative variable as false.
Remove markdown injection for block comments
Closes https://github.com/rust-lang/rust-analyzer/issues/15091
I tried making it work but it doesn't seem possible, as the `*` of the closing `*/` sequence gets eaten by the markdown grammar no matter what.
