  1. svsm: Introduce vscode settings file 

    Add .vscode/settings.json that correctly configures the vscode Rust
analyzer and ignores git repositories for all submodules to improve
developer experience for people using vscode.

  2. svsm/edk2: Introduce OVMF as submodule and build 

    COCONUT-SVSM requires a build of OVMF that supports booting via an SVSM
module. A default OVMF X64 firmware does not include this capability.
Therefore, rather than instructing the developer how to clone and
prepare a build of EDK2/OVMF, this patch adds the correct EDK2
repository and branch as a submodule and builds it as part of the SVSM
makefile.

  3. svsm/ovmf: Refactor OVMF guest code into module 

    COCONUT-SVSM currently exclusively launches guests under OVMF. However, we
should not assume this will always be the case. With this in mind, and
also to prepare for integrating the SVSM build with OVMF the current
OVMF specific code has been refactored into a module to abstract
specific steps away from svsm.rs.

If another guest firmware is required in the future, it will be quite
simple to create a trait from the ovmf_fw/OvmfFw structure to limit any
changes required to the main SVSM module.
