mlek: Update MLEK version and refactor patches

This commit include the following changes:

* Update MLEK library to latest release v24.05

* EthosU configurable arch patch is removed as
the issue of the constant NPU ID `u55` has been
fixed as part of v24.05 release.

* Use case resources patch is modified as the user
configurable use case resource file part of the patch
was added to v24.05 release where the remaining part
(user defined downloaded resources path) is to be available
in v24.08 release.

* tensorflow patch removed as the version of tensorflow
dependency the new MLEK v24.05 use doesn't need this
patch.

* activation_buf_dram placement in .bss.NoInit region patch
is removed to follow what MLEK library do regarding placement
of the activation buffers in the respective linker files for
each platform. This requires modification of all FRI
supported platforms' linker files.

* SetupMlEmbeddedEvaluationKitLibraries.cmake is modified to
adapt to v24.05 release changes.
