revert(components): remove misleading darwin entries for MicroVM providers

Slice B (commit a02045e) added darwin-amd64 / darwin-arm64 entries in the
`external` section and x86_64-darwin / aarch64-darwin in the `capsules`
section for `shell`, `localhost-provider`, `did-provider`, and
`webspace-provider`. Those entries told the install system "this
type: microvm capsule runs natively on Mac" while the runtime was
actually launching them as plain host-binary subprocesses without
microVM isolation — a silent downgrade of the isolation contract those
capsules declare, in violation of PRINCIPLES.md #10 (One Canonical
Path) and #11 (Fail Closed, Then Explain).

This revert restores manifest truth ahead of the Apple
Virtualization.framework backend project (docs/vz-backend/PLAN.md),
which is the principled path to making Mac a first-class ElastOS host
with identical microVM isolation to Linux/KVM.

On Mac, `elastos setup --list` will now correctly report these capsules
as "not available for darwin-arm64", and capsule launch fails closed
with the existing supervisor message rather than degrading silently.

Unchanged: the rest of Slice B's daemon-portability work
(pid_is_alive, ELASTOS_DATA_DIR, smoke-script Bash 3.2 portability,
elastos-crosvm cfg-gated non-Linux build, darwin-arm64 platform
identity, universal-platform demo capsule installs) is kept — none of
that touches the Linux microVM substrate.

No Linux behaviour change.
