FIX: expose Edb deprecations statically for grpc and dotnet backends

[svandenb-dev]

This PR makes deprecated PyEDB APIs visible to static analysis tools and IDEs across the package, while preserving the existing runtime deprecation warnings.
The original issue was first observed with top-level backend selection:

from pyedb import Edb

edb = Edb(edbpath="my_project.aedb", grpc=True)
edb.save_edb()

In this case, deprecation warnings were active at runtime, but PyCharm did not show methods like save_edb() as deprecated.
Root cause
PyEDB already had runtime deprecation decorators:

• deprecated
• deprecated_property
• deprecated_class
  However, those decorators only emitted warnings at runtime and did not provide a standard static deprecation path for IDEs/type checkers.
  There was also a typing aspect:
• the top-level Edb overload path needed to resolve clearly to the concrete backend classes so IDEs could inspect the right API surface for grpc=True and grpc=False.

What changed

1. Package-wide deprecation metadata via shared decorators
   Updated the shared deprecation helpers in:

• src/pyedb/misc/decorators.py
• src/pyedb/misc/decorators.pyi
  so that deprecated symbols expose static deprecation metadata in addition to runtime warnings.
  This allows existing deprecated APIs across the package to benefit from a centralized solution rather than patching each file independently.

2. Top-level Edb stub resolution
   Updated:

• src/pyedb/init.pyi
• src/pyedb/generic/design_types.pyi
  so the overloads resolve directly to the concrete backend classes:
• gRPC backend
• dotnet backend
  This improves IDE inference for top-level usage:

from pyedb import Edb

and makes backend-specific deprecated members discoverable.
3. Backend-specific deprecated APIs
Added static deprecation coverage for deprecated Edb APIs in:

• src/pyedb/grpc/edb.py
• src/pyedb/dotnet/edb.py
  Added and extended integration coverage in:
• tests/integration/test_edb_deprecation_metadata.py

closes #1981
