Improve component install feature

Component install is a nice feature but it could be improved upon for more ease of use and usefulness.

project is a 4 installable component project, with comp4 part of EXCLUDE_FROM_ALL

1. Multi comnponent install

cmake --install ./ --component comp1,comp2,comp3,comp4

install all four components

2. Exclude component from command line

cmake --install ./ --exclude-component comp3

install comp1 and comp2

3. List available component (do not perform install but list components only)

cmake --install ./ --list-components

comp1
comp2
comp3
comp4 (EXCLUDE_FROM_ALL)

4. Install everything even EXCLUDE_FROM_ALL

cmake --install ./ --even-exclude-from-all

Of course, this is some usecases that came into my mind, maybe this is not realistic, maybe other usecases should be supported.
