When processing an indirect dependency of target `A` on target `C` via
an interface library B, `cmComputeTargetDepends::AddTargetDepend` was
not checking for duplicate dependencies, so that if `A` depended on `C`
via multiple interface libraries, the dependency graph built in
cmComputeTargetDepends would have duplicate edges. In a real project
(LLVM libc) this was causing cmake to consume multiple gigabytes of RAM.

Since commit 5420639a8d (cmExecuteProcessCommand: Replace cmsysProcess
with cmUVProcessChain, 2023-06-01, v3.28.0-rc1~138^2~8) we have not
actually terminated child processes on an `execute_process` timeout.
Similarly for other migrations from cmsysProcess to cmUVProcessChain.
Teach cmUVProcessChain clients that implement timeouts to actually
terminate remaining child processes when the timeout is reached.

When setting the installation prefix at the installation phase
(`cmake --install`) using the `--prefix` option, the GNU special cases
aren't applicable. This also adds a small clarification when to use the
`--prefix` option at the installation phase.
Briefly mentioned also the CMake presets installDir field,
the CPACK_PACKAGING_INSTALL_PREFIX variable, and the $<INSTALL_PREFIX>
generator expression so user has a better overview.
