install: Implement new install(CODE|SCRIPT) option ALL_COMPONENTS

Browse Source 
In a per-component installation the generated installation scripts
are invoked once for each component.

Per default custom installation script code added by install(CODE|SCRIPT)
only runs for one specific component in this context.

The new ALL_COMPONENTS option allows custom script code to be run once
for each component being installed.
