Adds the following keys to ccmake:
- w: writes changes to cache file and quits without generating
- N: jump to previous search result
- Home: jump to first option
- End: jump to last option
Read `CMAKE_CROSSCOMPILING_EMULATOR` from an environment variable of the
same name if not specified with `-D` or an initial cache value.
Along with existing environment variable settings such as
`CMAKE_TOOLCHAIN_FILE`, cross compilation configuration can be more
completely set via environment variables.

This was regressed by refactoring in commit e08ba229ee (CMake code rely
on cmList class for CMake lists management (part. 1), 2023-04-14,
v3.27.0-rc1~174^2). Fix it and add a test case.
Fixes: #24986
Previously, we were letting libuv create the output pipe for each
process. However, in order to facilitate use cases where process
spawn is expected to fail (in the case of a missing executable), we
want pipe creation to be separate from process creation. Manually
create all of the pipes.
Move most of cmUVProcessChain::InternalData::Finish() to Prepare()
so that error codes can be checked before attepting to spawn any
processes. Check some error codes that weren't being checked before.
Change return type of Finish() to void as it can't fail.
This handles the case where `COLOR` is set to some ANSI-like color
sequence in the ambient environment. These sequences tend to include `;`
which terminates the command and tries to use the next component
(typically an integer, possibly with a trailing `m`) with errors like:
/bin/sh: line 1: 2: command not found
/bin/sh: line 1: 255: command not found
/bin/sh: line 1: 221: command not found
/bin/sh: line 1: 255m: command not found
Also add a test that sets `COLOR` in the environment which affects the
generated Makefiles behavior.

The files generatd by `install(EXPORT)` and `export()` commands
are known to work with policies as of CMake 3.26, so enable them
in sufficiently new CMake versions.
The OLD behaviors of all policies are deprecated, but only by
documentation. Add an explicit deprecation diagnostic for policies
introduced in CMake 3.20 and below to encourage projects to port
away from setting policies to OLD.
