trop[bot] 44ebbc11ed refactor: replace CHILD_PLUGIN with CHILD_EMBEDDER_FIRST on macOS (#50321)
refactor: replace CHILD_PLUGIN with CHILD_EMBEDDER_FIRST on macOS

Chromium removed upstream support for child plugin processes without
library validation in https://crbug.com/461717105, which we patched
back via feat_restore_macos_child_plugin_process.patch.

Chromium's CHILD_EMBEDDER_FIRST mechanism already provides the right
extensibility point for this: values > CHILD_EMBEDDER_FIRST are reserved
for embedders and resolved via ContentBrowserClient::GetChildProcessSuffix().
Chrome itself uses this pattern for its Alerts helper process.

This commit replaces the Chromium patch with an Electron-native
implementation.
