[bug] cmake_find_package generated file doesnt honor CONAN_CMAKE_SILENT_OUTPUT

Environment Details (include every applicable attribute)

• Operating System+version: not applicable
• Compiler+version: not applicable
• Conan version: everything released
• Python version: not applicable

Steps to reproduce (Include if Applicable)

with cmake-conan at least when issuing following command:

cmake -GNinja -DCONAN_CMAKE_SILENT_OUTPUT $buildpath

and having cmake_find_package generator enabled in conanfile or passed in to conan_cmake_run(), generated Find$package.cmake has a single message() call. Since the bug is essentially here:

https://github.com/conan-io/conan/blob/develop/conans/client/generators/cmake_find_package.py#L9

Same will most likely happen with calling conan install too..

When cmake 3.17 or never, these could be removed by filtering on the log level but that is not option for everybody.

Logs (Executed commands with output) (Include/Attach if Applicable)

Excessive output like this will be shown when generating build scripts:

-- Conan: Using autogenerated FindYYY.cmake
-- Conan: Using autogenerated FindZZZ.cmake

Hi, @rasjani Thanks for reporting and thanks for submitting the PR, I agree with you that all the output generated by Conan should be silenced by CONAN_CMAKE_SILENT_OUTPUT variable.
