`CopyADirectory`.

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.
Fixes: #27378
Since commit 5420639a8d (cmExecuteProcessCommand: Replace cmsysProcess
with cmUVProcessChain, 2023-06-01, v3.28.0-rc1~138^2~8) we've
occasionally observed immediate timeouts on processes that take longer
than the timeout to start, even though we only start the timer after the
child processes start. The problem is that:
* `uv_loop_init` initializes `uv_loop_t`'s cached "now" time.
* Starting processes takes time but does not update the "now" time.
* `uv_timer_start` computes expiry relative the cached "now" time,
so short timers may be expired as soon as they are started.
* `uv_run` invokes expired timer callbacks before polling for I/O
or process completion, so we "timeout" immediately.
Fix this by updating the cached "now" time via `uv_update_time` just
before starting timers. This is needed only for timers that start
before the `uv_run` event loop. Update our `uv_timer_ptr` wrapper
to make all callers consider the choice when calling `start()`.
We normalize directory paths to not end in `/`. However, a root
directory path always ends in `/`. Avoid removing the first character
after it.

Remove the unnecessary `FindProgramPath` wrapper. Call the KWSys
`FindProgram` directly, without our CMake-specific wrapper, since
we follow-up with a `ToNormalizedPathOnDisk` anyway.
KWSys's `FindProgram` no longer looks up the actual case on disk. This
behavior change was inherited from the change to `CollapseFullPath`.
Extend commit 773b75e4ed (cmake: Explicitly look up on-disk case of
input paths on Windows, 2024-10-23, v4.0.0-rc1~589^2) to cover this by
wrapping `FindProgram` in a CMake-specific layer.

This was accidentally dropped by commit 622596c6b2 (cmSystemTools:
Re-implement ToNormalizedPathOnDisk without translation map, 2024-10-30,
v4.0.0-rc1~528^2~5). Previously it was done by `CollapseFullPath`.
`cm::PathResolver` intentionally does not expand `~` because it makes
sense only for transforming input paths. Teach `ToNormalizedPathOnDisk`
to handle it directly.

In commit 823e1df54c (cmSystemTools: Implement GetRealPath on Windows,
2024-11-04, v4.0.0-rc1~521^2~1) we implemented the POSIX behavior that
resolves symlinks followed by '..' components. However, Windows just
removes them lexically. Also, we were not handling all junction types.
Instead, use `GetFinalPathNameByHandleW` via `uv_fs_realpath`.
Note that we previously attempted this in commit 640709e7db
(cmSystemTools: Implement GetRealPath on Windows, 2017-10-02,
v3.11.0-rc1~445^2~1) but reverted it in commit 83630d4918
(cmSystemTools: Revert GetRealPath implementation on Windows,
2018-05-29, v3.11.3~3^2) due to resolving `subst` drives. This time,
add code to re-`subst`itute the drive in the resolved path.

Since commit 622596c6b2 (cmSystemTools: Re-implement
ToNormalizedPathOnDisk without translation map, 2024-10-30,
v4.0.0-rc1~528^2~5) we normalize input paths, while resolving symlinks
only if followed by `..` components, by using `cm::PathResolver`'s
`LogicalPath` mode. However, that approach assumes POSIX semantics for
resolving paths with symlinks and is incorrect on Windows.
On Windows, file system operations naively remove any component
preceding `..` regardless of whether it is a symlink. Prior to the
above commit, `ToNormalizedPathOnDisk` matched that behavior using
`CollapseFullPath` followed by `GetActualCaseForPath`. Restore it using
`cm::PathResolver`'s `CasePath` mode.

Extend the fix from commit 74c9d40876 (execute_process: Fix invocation
of .cmd/.bat with spaces, 2025-01-31) to work without relying on
conversion to a "short path", which may not exist. Instead, extending
the `cmd /c` wrapper to `cmd /c call` seems to support spaces directly.

When profiling Qt builds on macos, about 2.2% of a `cmake` invocation
was spent reading from `/dev/urandom`. Use a (thread)local rng to
mitigate this cost, particularly in `cmGeneratedFileStreamBase::Open`.
Most Unix-like systems drops the SETUID/SETGID bits when a file changes,
so after changing the RPATH, it is necessary to restore
the original file mode.
