Brad King ff1693cb3c cmGeneratorTarget: Clarify enum for specifying purpose of usage requirements 
Since commit 1e49880472 (cmGeneratorTarget: Avoid boolean trap in usage
requirement lookup, 2021-12-08, v3.23.0-rc1~245^2) we have clarified
the distinction between compile-only and link-only usage requirements.
Rename the `LinkInterfaceFor` enum to `UseTo` to clarify that its role
is to specify the purpose of usage requirements.

Brad King ef006ebd9b PCH: Use per-arch .pch files only when building multiple Apple architectures 
Since commit f593b354da (PCH: Add support for multi architecture iOS
projects, 2020-04-02, v3.18.0-rc1~414^2) we use per-arch .pch files
even when compiling for just the host architecture on macOS arm64.
This breaks with compilers that do not support `-Xarch_` flags, such
as GCC.  Avoid using per-arch .pch files in single-architecture builds.

Brad King ddb9442f48 GenEx: Fix TARGET_PROPERTY evaluation of transitive link properties 
In commit bbba701899 (Link properties: must be transitive over private
dependency on static library, 2019-12-06, v3.17.0-rc1~323^2) and
commit af9d4f24ae (Link properties: must be transitive over private
dependency on static library, 2019-12-11, v3.17.0-rc1~305^2) we
neglected to implement CMP0099 NEW behavior for `TARGET_PROPERTY`
evaluation.  Add policy CMP0166 to fix this.
