Merge | AssemblyCache

[benrr101]

Description: Moving one small class from netfx project to common project. I made a couple changes to it along the way:

• Removed comments that make literally no sense anymore
• Made the class static (it only has two static methods in it anymore)
• Couple low-impact stylistic changes

Change In Plans! Let's just get rid of AssemblyCache! The two remaining methods in the class have been rolled into the respective class they were called in. GetSize was rolled into SqlParameter (only place it was used), GetType was rolled into SqlConnection (which now matches netcore implementation). AssemblyCache was deleted.

Testing: Just moving things around. Still no funny business here.

[nitpick] Consider updating the assertion message to include an apostrophe (e.g. "Type object can't be null") for clarity.

Suggested change

	Debug.Assert(t != null, "Type object cant be NULL");
	Debug.Assert(t != null, "Type object can't be NULL");

Looks good as is for a pure move. But I also agree with @edwardneal 's method cleanup suggestion.

Pull Request Overview

This PR removes the AssemblyCache class and its usages, merging its remaining functionality directly into SqlConnection and SqlParameter.

• Removed dependency on AssemblyCache in SqlConnection by inlining the GetInfoFromType logic.
• Updated SqlParameter to call SerializationHelperSql9.SizeInBytes instead of using the AssemblyCache branch.
• Deleted the AssemblyCache source file.

• [nitpick] Consider renaming GetInfoFromType to GetSqlUdtInfoFromType to more clearly indicate its purpose.

SqlUdtInfo attr = GetInfoFromType(o.GetType());

• Verify that SerializationHelperSql9.SizeInBytes handles all cases previously managed by AssemblyCache.GetLength, particularly on the NETFX target.

coercedSize = SerializationHelperSql9.SizeInBytes(val);
