Set some CMakeDeps properties from consumer

[czoido]

Changelog: Feature: Provide the ability to set CMakeDeps properties from consumer side.
Docs: conan-io/docs#2827

Gives you the possibility to overwrite some properties set in dependencies in CMakeDeps: cmake_file_name, cmake_target_name, cmake_find_mode, cmake_module_file_name and cmake_module_target_name

The interface is:

def generate(self):
    deps = CMakeDeps(self)
    deps.set_property("<dep>", "cmake_find_mode", "module")
    deps.set_property("<dep>::<component>",  "cmake_target_name", "mycompname")
    deps.generate()

for the cases with build_context_activated:

def generate(self):
    ...
    deps = CMakeDeps(self)
    deps.set_property("<dep>", "cmake_find_mode", "module", build_context=True)
    deps.set_property("<dep>::<component>",  "cmake_target_name", "mycompname", build_context=True)
    deps.generate()
    ...

You can also invalidate from consumer the properties set upstream assigning a None:

def generate(self):
    ...
    deps.set_property("<dep>", "cmake_module_target_name",  None)

Closes: #12534
Close #7118

Looks good, clean and promising to deliver something useful.
A couple minor things to discuss, good job.

Looks very promising for conan-center as well, to avoid breakage in recipes when their dependencies break these properties (for example when suddenly a new version of a library implements a CMake config file, we have to update these names in this recipe, but it can break downstream recipes which were relying on default values <recipeName>-config.cmake & target <recipeName>::<recipeName>).
