[release/8.0.1xx] Remove CA2229 Implement serialization constructors

[github-actions]

Backport of #6911 to release/8.0.1xx

/cc @buyaa-n

Customer Impact

Hidden rule CA2229: Implement serialization constructors, can be enabled specifically by ID or can be enabled as part of bulk configuration. Starting in .NET 8 SYSLIB0051: Legacy serialization support APIs are obsolete generates warning at compile time for the serialization constructors (and also for other BF related APIs) therefore conflicts with CA2229.

As Binary formatters are deprecated in .NET Core CA2229 is also out dated and can be removed.

Testing

NA, removing the analyzer entirely

Risk

Very low:

• CA2229 could be useful for .NET framework users that are referencing NetAnalyzers manually. If they still need the analyzer, they could keep using the older versions.
• CA2229 also could be useful .NET core users that opt in using BF. Though BF is going to be removed from .NET 9 anyways.

For both cases even if they missed adding the constructor a basic app testing would uncover such a bug, so it is less risky.

This is approved for .NET 8 RC2 since it is related to the BinaryFormatter obsoletion strategy and this analyzer was found to contradict the guidance we now provide.
