Fix broken cpp_info.location deduction due to unsanitized regex

Changelog: Fix: Fix broken cpp_info.location deduction due to unsanitized regex.
Docs: Omit

Using grpc with -c tools.cmake.cmakedeps:new=will_break_next currently fails with:

ConanException: grpc/1.67.1: Cannot obtain 'location' for library 'grpc++_alts' in ['/home/martin/.conan2/p/b/grpcad62ea78a9235/p/lib']. You can specify 'cpp_info.location' directly or report in github.com/conan-io/conan/issues if you think it should have been deduced correctly.

This PR fixes the location detection failure due to the unsanitized + symbols in the library name.

The location detection could be improved further, still. It should fall back to the fuzzy regex only if an exact match is not found.

grpc/1.67.1: WARN: There were several matches for Lib grpc: ['lib/libgrpc.so.44.0.0', 'lib/libgrpc_authorization_provider.so.1.67.1', 'lib/libgrpc_plugin_support.so.1.67.1', 'lib/libgrpc_unsecure.so.44.0.0']

Unrelated, but too minor for a separate issue - using grpc with the new CMakeDeps still fails after this fix with

  File "/home/martin/libs/conan/conan/tools/cmake/cmakedeps2/target_configuration.py", line 169, in _get_cmake_lib
    self._conanfile.output.warning("frameworks not supported yet in new CMakeDeps generator")
    ^^^^^^^^^^^^^^^^^^^^^^

Thanks for your contribution.

We would like to start first with some unit test that would fail without this change. This is the best way to move forward without breaking the addressed issue because is not properly covered.

Agree, if you want you can just replace that with a ConanOutput(scope=str(self.conanfile)).warning() or something like that, this doesn't require test coverage yet, as it is just a temporary warning until the frameworks are implemented.

Merged, thanks for the contribution, it will be in next Conan 2.11
