[OE-core] [PATCH] cmake: refactor compile and install for easier re-use

[André Draszik]

From: André Draszik <andre.draszik at jci.com>

cmake_do_compile() and cmake_do_install() basically do the
same, except they use a different --target, and at the
moment this is copy/pasted code with a minor modification.

Other recipes which e.g. might want to support compilation
as part of ptest have to do the same. This is a bit
inconvenient.

By factoring out all of this into a common helper,
cmake_runcmake_build(), this is easily re-used. An
(imaginary) recipe can compile ptest support simply by
using
  cmake_runcmake_build --target buildtest-TESTS
(assuming such a build target exists).

Also, this now is very similar to oe_runmake().
