[package] grpc/1.65.0: downstream builds break if absel is used as shared

[weatherhead99]

Description

When building a package which depends on gRPC, and using abseil as a shared library, downstream builds can break with an error like (on gcc):

undefined reference to symbol '_ZN4absl12lts_2024011612log_internal17MakeCheckOpStringImmEEPNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEET_T0_PKc'
/usr/lib64/gcc/x86_64-suse-linux/13/../../../../x86_64-suse-linux/bin/ld: /home/danw/.conan2/p/b/absei344124e3560e9/p/lib/libabsl_log_internal_check_op.so.2401.0.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

or similar. In the recipe for gRPC, the self.requires statement for abseil correctly adds the "transitive_headers=True" trait. It should also add the "transitive_libs=True", because downstream consumers need to link to the abseil shared library.

This is not true for static library usage, but unfortunately I don't see a way to detect whether abseil is a shared library at this point in the build. Using self.options['abseil'].shared doesn't seem to work, and of course `self.dependencies' doesn't exist at the time of the 'requirements()' method being called.

Steps to reproduce

create package which uses grpc/1.65.0 as a dependency conan build . -oabseil/*:shared=True --build=missing

package build fails with missing DSO from command line related to absl
