meson: Add build option for tools

Add a build option to control building some of the misc tools we
have. Also set the executables to install, presumably you want
that if you're asking for the build.

v2: set 'install:' to the with_tools value, not true (Jordan)
    handle 'all' in a the comma list (Dylan)
    Add freedreno's tools (Dylan)
