Commits on Sep 11, 2024

  1. Add CMake package config file 

    This change enables automatic detection and consumption of Mbed TLS
library targets from within other CMake projects. By generating an
`MbedTLSConfig.cmake` file, consuming projects receive a more complete
view of these targets, allowing them to be used as dependencies which
properly inherit the transitive dependencies of the libraries.

This is fairly fragile, as it seems Mbed TLS's libraries do not appear
to properly model their dependencies on other targets, including
third-party dependencies. It is, however, sufficient for building and
linking the compiled Mbed TLS libraries when there are no third-party
dependencies involved. Further work is needed for more complex
use-cases, but this will likely meet the needs of most projects.

Resolves Mbed-TLS#298. Probably useful for Mbed-TLS#2857.

This commit is modified in the backport over the original to consider:
  - 1f0cdaf Stop dispatching through obsolete functions
  - 3bc3409 Remove obsolete cd at the end of a component
