The NDK build system now uses only a single toolchain in
<ndk>/toolchains/llvm/prebuilt/<host>
Its compilers are always `bin/{clang,clang++}` and its binutils are
always `bin/<triple>-*`. It is a standalone toolchain:
* The Anrdoid API level is specified at the end of `--target=`.
* The standard library may be specified via `-stdlib=`.
* No need to pass system includes or libraries explicitly.
* No need to pass `--sysroot` or `-gcc-toolchain`.
Teach CMake to recognize NDK versions that have a unified
toolchain with its own sysroot and use the above approach.
Fixes: #18739
- Remove code signing requirements for non-macOS
- Do not set deployment target for non-macOS
- Build static library for compiler feature detection for non-macOS
- Use framework to run CompilerId tests for watchOS
- Port tests to new SDK handling
- Add new Apple cross-compiling section to toolchain documentation
Closes: #17870
The unified headers are preferred as of NDK r15, so use them by default
if available and provide an option to use the deprecated headers.

Fixes: #16584
When this variable is not set by the user or toolchain file, set it to
the default selected. This will be useful for client code that needs to
pass the value to an external tool that needs to find the same toolchain
in the NDK. Leave it empty for a standalone toolchain.

CMake now supports cross compiling for Android using the NDK or a
standalone toolchain. Document the associated variables and how how to
write toolchain files for Android.
We originally deprecated this module in commit v3.5.0-rc1~295^2
(CMakeForceCompiler: Deprecate this module and its macros, 2015-10-19).
Then a use case was found to still require the module so the deprecation
was reverted for CMake 3.5 by commit v3.5.0-rc3~4^2 (CMakeForceCompiler:
De-deprecate until more use cases have alternatives, 2016-02-17). Since
then `CMAKE_TRY_COMPILE_TARGET_TYPE` was introduced to provide an
alternative solution for that use case. Deprecate the module again.
Extend the Nsight Tegra project generator to add bunch of properties
with the backing variables to fine-tune the generated projects.
Add target properties that map to all "Configuration" PropertyGroups for
each configuration:
* ANDROID_ARCH
* ANDROID_STL_TYPE
Add target properties that map to the AntBuild section of vcxproj files:
* ANDROID_ANT_ADDITIONAL_OPTIONS
* ANDROID_ASSETS_DIRECTORIES
* ANDROID_JAR_DEPENDENCIES
* ANDROID_JAR_DIRECTORIES
* ANDROID_JAVA_SOURCE_DIR
* ANDROID_NATIVE_LIB_DEPENDENCIES
* ANDROID_NATIVE_LIB_DIRECTORIES
* ANDROID_PROCESS_MAX
* ANDROID_PROGUARD
* ANDROID_PROGUARD_CONFIG_PATH
* ANDROID_SECURE_PROPS_PATH
* ANDROID_SKIP_ANT_STEP

Also add a 'CMAKE_ANDROID_API_MIN' variable to set the property
default. Teach the VS generator to write the MIN API value into
Nsight Tegra project files.
Update the wording of some examples to avoid long lines in code blocks.
Otherwise the formatted documentation can exceed certain column width
limitations.
