Add support for component aliases

Introduce concept of component aliases, which act as an alternative way
for referring a set of related components.

Component aliases are declared in an alias definition file, which is
included to the created installer's binary layout as a resource. The
file lists the available aliases, including metadata - such as name,
version, and description - and the list of components and other aliases
the alias requires.

Aliases can be referred only from the CLI for the time being, with the
supported commands 'install' and 'search'.
