Subject: Add version suffix for all installable targets

Convert main library targets to slottable versions. This allows to
install major versions of MbedTLS simultaneously.

Dependent packages should use `find_package(MbedTLS 3 [REQUIRED])` and
`MbedTLS::<component>` in order to use requested libraries.
