[bug] NDK path with spaces doesn't work in CMakeToolchain

[kambala-decapitator]

Describe the bug

macOS 14.7, Conan v2.9.2

If NDK path contains spaces, then it's inserted in the toolchain file as is and cmake doesn't like it of course. Example:

conan install -c tools.android:ndk_path=/Volumes/Android\ NDK\ r27c/AndroidNDK12479018.app/Contents/NDK ...

then at cmake configure time there'll be error like:

CMake Error at conan-android64-25/conan_toolchain.cmake:39 (include):
  include called with invalid argument:
  r27c/AndroidNDK12479018.app/Contents/NDK/build/cmake/android.toolchain.cmake
Call Stack (most recent call first):
  /Users/kambala/dev/vcmi/build-android64/CMakeFiles/3.31.0/CMakeSystem.cmake:6 (include)
  CMakeLists.txt:6 (project)

Embedding quotes inside the path also doesn't help:

conan install -c tools.android:ndk_path='"/Volumes/Android NDK r27c/AndroidNDK12479018.app/Contents/NDK"' ...
...
CMake Error at conan-android64-25/conan_toolchain.cmake:39 (include):
  include requested file is a directory:

    /Volumes/Android NDK r27c/AndroidNDK12479018.app/Contents/NDK
Call Stack (most recent call first):
  /Users/kambala/dev/vcmi/build-android64/CMakeFiles/3.31.0/CMakeSystem.cmake:6 (include)
  CMakeLists.txt:6 (project)

Adding the config to a profile instead results in exactly the same issues.

How to reproduce it

pass -c tools.android:ndk_path='/some/path with spaces' to conan install and check the generated toolchain file or try to configure a CMake project with it
