const correctness for public interfaces in MemoryManagedResource

[ShoroukRamzy]

Description

This pull request solves this issue (eclipse-score/communication#84) and improves the API safety and robustness of the score::memory::shared library by enforcing const-correctness on key methods. The primary goal is to prevent accidental modification of internal bookkeeping data within shared memory segments, which could lead to memory corruption.

The following key changes have been implemented:

const Return Types and Methods:

ManagedMemoryResource::getBaseAddress() now returns const void*. This protects the underlying ControlBlock from being modified by external callers.
ManagedMemoryResource::getMemoryResourceProxy() now returns const MemoryResourceProxy* and is a const method. This ensures the integrity of the proxy's identifier.

Derived Class and Mock Updates:

All classes inheriting from ManagedMemoryResource or ISharedMemoryResource (including SharedMemoryResource, NewDeleteDelegateMemoryResource, and all test mocks/fakes) have been updated to correctly override the new const-correct signatures.

Call Site Adjustments:

All call sites that invoke getBaseAddress() or getMemoryResourceProxy() have been updated to correctly handle the const return types.
const_cast has been used in a few specific, controlled instances (primarily in test fakes interacting with the MemoryResourceRegistry) to maintain compatibility with older APIs that were not yet const-aware. This was a pragmatic choice to limit the scope of the refactoring while still achieving the primary safety goal.

How to Test

Build the score/memory library and its dependencies:
bash
bazel build --config=bl-x86_64-linux //score/memory/...
Run all associated tests to ensure no regressions have been introduced:
bash
bazel test --config=bl-x86_64-linux //score/memory/...
All tests should pass, confirming that the const-correctness changes have been applied consistently and correctly throughout the library and its test suite.
