build: remove unneeded function versioning

build: remove unneeded function versioning

Timer, LPM and Distributor libraries no longer use function versioning
and therefore do not need separate build for static and shared version
of libraries.

This patch removes use_function_versioning from their meson build files
and corresponding include from the sources.
