* [NRBF] Don't use Unsafe.As when decoding DateTime(s) (#105749)

* Add NrbfDecoder Fuzzer (#107385)

* [NRBF] Fix bugs discovered by the fuzzer (#107368)

* bug #1: don't allow for values out of the SerializationRecordType enum range

* bug #2: throw SerializationException rather than KeyNotFoundException when the referenced record is missing or it points to a record of different type

* bug #3: throw SerializationException rather than FormatException when it's being thrown by BinaryReader (or sth else that we use)

* bug #4: document the fact that IOException can be thrown

* bug #5: throw SerializationException rather than OverflowException when parsing the decimal fails

* bug #6: 0 and 17 are illegal values for PrimitiveType enum

* bug #7: throw SerializationException when a surrogate character is read (so far an ArgumentException was thrown)
# Conflicts:
#	src/libraries/System.Formats.Nrbf/src/System/Formats/Nrbf/NrbfDecoder.cs

* [NRBF] throw SerializationException when a surrogate character is read (#107532)

 (so far an ArgumentException was thrown)

* [NRBF] Fuzzing non-seekable stream input (#107605)

* [NRBF] More bug fixes (#107682)

- Don't use `Debug.Fail` not followed by an exception (it may cause problems for apps deployed in Debug)
- avoid Int32 overflow
- throw for unexpected enum values just in case parsing has not rejected them
- validate the number of chars read by BinaryReader.ReadChars
- pass serialization record id to ex message
- return false rather than throw EndOfStreamException when provided Stream has not enough data
- don't restore the position in finally 
- limit max SZ and MD array length to Array.MaxLength, stop using LinkedList<T> as List<T> will be able to hold all elements now
- remove internal enum values that were always illegal, but needed to be handled everywhere
- Fix DebuggerDisplay

* [NRBF] Comments and bug fixes from internal code review (#107735)

* copy comments and asserts from Levis internal code review

* apply Levis suggestion: don't store Array.MaxLength as a const, as it may change in the future

* add missing and fix some of the existing comments

* first bug fix: SerializationRecord.TypeNameMatches should throw ArgumentNullException for null Type argument

* second bug fix: SerializationRecord.TypeNameMatches should know the difference between SZArray and single-dimension, non-zero offset arrays (example: int[] and int[*])

* third bug fix: don't cast bytes to booleans

* fourth bug fix: don't cast bytes to DateTimes

* add one test case that I've forgot in previous PR
# Conflicts:
#	src/libraries/System.Formats.Nrbf/src/System/Formats/Nrbf/SerializationRecord.cs

* [NRBF] Address issues discovered by Threat Model  (#106629)

* introduce ArrayRecord.FlattenedLength

* do not include invalid Type or Assembly names in the exception messages, as it's most likely corrupted/tampered/malicious data and could be used as a vector of attack.

* It is possible to have binary array records have an element type of array without being marked as jagged
