Manage third-party projects

• Issue
  • Redundant forked repos (islet-build, islet-linux)
  • Almost sub-modules needs to be modified (tf-a, tf-a-tests, build)
• Solution: Use worktree which manages multiple working trees

Before

~/islet (main) $ tree -L 1
. 
├── assets # submodule
├── build # submodule, forked, modified
├── guest-linux # submodule
├── linux # submodule, forked, modified
├── trusted-firmware-a # submodule, modified
└── upstream-trusted-firmware-a # submodule

After

~/islet (rfc) $ tree -L 2
.
├── assets # submodule
├── third-party
│   ├── nw-linux # worktree
│   ├── optee-build # worktree
│   ├── realm-linux # worktree
