Improvements to C# analysis

The following changes in version 1.26 affect C# analysis in all applications.

New queries

Query	Tags	Purpose

Query	Expected impact	Change
Weak encryption: Insufficient key size (`cs/insufficient-key-size`)	More results	The required key size has been increased from 1024 to 2048.

Partial method bodies are extracted. Previously, partial method bodies were skipped completely.
Inferring the lengths of implicitely sized arrays is fixed. Previously, multidimensional arrays were always extracted with the same length for each dimension. With the fix, the array sizes 2 and 1 are extracted for new int[,]{{1},{2}}. Previously 2 and 2 were extracted.
The extractor is now assembly-insensitive by default. This means that two entities with the same fully-qualified name are now mapped to the same entity in the resulting database, regardless of whether they belong to different assemblies. Assembly sensitivity can be reenabled by passing --assemblysensitivetrap to the extractor.
