IJPL-257728 removed intellij.platform.kernel, kernel.impl and kernel.backend
from the platform. On builds from master, IdeaVIM.ideavim-backend and both
bookmark backend modules declared a dependency on intellij.platform.kernel.backend,
so the platform skipped them silently. None of the remoteApiProvider extensions
got registered, and Commentary, Format and the other RPC calls failed with
"No remote API found".
IdeaVim doesn't use any class from these modules. The backend-only loading in
split mode is still provided by the dependency on intellij.platform.backend.

intellij.platform.rpc doesn't exist in 2025.3, is embedded in the core
classloader in 2026.1-2026.2 and is a standalone module since 2026.3.
Declaring it as a dependency of the embedded ideavim-common module disables
the whole plugin on 2025.3 and breaks the 2025.3 build.
Move the dependency to a new optional ideavim-rpc module that provides
VimRemoteApiResolver via the IdeaVIM.remoteApiResolver extension point.
When the module is skipped (2025.3), fall back to calling
RemoteApiProviderService from the core classloader.
