docs: Update outdated intel_tdx.md

TDX homepage was moved to elsewhere, and `tdx-tools` repo was removed.

Provide a valid link of TDX homepage and change all reference to
`tdx-tools` to `tdx-linux`.

Format `intel_tdx.md` using `mdformat` with GitHub Flavored Markdown
(GFM).

 Cloud Hypervisor can run TDX VM (Trust Domain) by loading a TD firmware ([TDVF](https://github.com/tianocore/edk2)),
 which will then load the guest kernel from the image. The image must be custom
 as it must include a kernel built from the [Guest TDX tree](https://github.com/intel/tdx/tree/guest).
