Fix numeric IntPtr behavioral changes analyzer findings

[buyaa-n]

With #74022 we are adding an analyzer that detects behavioral changes in built operators of numeric IntPtr feature. Some built in operators added added with the feature behave differently than the old user defined operators. Some operators that used to throw in unchecked context while overflowing will not throw anymore unless wrapped within checked context, and some operators that not used to throw in checked context now would unless wrapped within unchecked context.

Normally we would merge the analyzer to the roslyn-analyzers repo first then update the dogfooding version and along with code fixes, but as the analyzer still not merged yet but it still planned to be merged into 7.0 raising this PR without the analyzer dogfood version updates

How the warnings handled?

• Wrapped within checked expression in case the overflowing seems needs to be experienced
  • When the IntPtr/UintPtr used as a pointer
  • When the explicit casting to long is used on purpose (IntPtr)(((long)pNative) - sizeof(uint))
• Used nint/nuint alias in case the IntPtr/UintPtr seems not used as a pointer
• in some rare cases suppressed the warning (could not use the alias because it is an public API)
• in some rare case changed the IntPtr to real pointer (void*), this is desired when the IntPtr is used as real pointer, but changing the type like this require much more code change which I am not sure if we want to update

Issue Details

---

With #74022 we are adding an analyzer that detects behavioral changes in built operators of numeric IntPtr feature. Some built in operators added added with the feature behave differently than the old user defined operators. Some operators that used to throw in unchecked context while overflowing will not throw anymore unless wrapped within checked context, and some operators that not used to throw in checked context now would unless wrapped within unchecked context.

Normally we would merge the analyzer to the roslyn-analyzers repo first then update the dogfooding version and along with code fixes, but as the analyzer still not merged yet but it still planned to be merged into 7.0 raising this PR without the analyzer dogfood version updates

How the warnings handled?

• Wrapped within checked expression in case the overflowing seems needs to be experienced
  • When the IntPtr/UintPtr used as a pointer
  • When the explicit casting to long is used on purpose (IntPtr)(((long)pNative) - sizeof(uint))
• Used nint/nuint alias in case the IntPtr/UintPtr seems not used as a pointer
• in some rare cases suppressed the warning (could not use the alias because it is an public API)
• in some rare case changed the IntPtr to real pointer (void*), this is desired when the IntPtr is used as real pointer, but changing the type like this require much more code change which I am not sure if we want to update

CC. @jkotas, you were particularly interested in the how some of this was changed.

[tannergooding]

I wonder if nint.Max(_rowFetchedCount, 0) would better match the intent or if explicitly truncating down to int was the intent...

[jkotas]

I have not found any place in the delta where checked arithmetic is desired. Many places can be simplified now that unchecked arithmetic is the default.

Update: The PR is almost ready, just waiting the analyzer PR got merged and built for dogfood, then I will add the update the runtime analyzer version with that build

2 of the failures related to #76280 and #76617
Failure on mono minijit Pri0 Runtime Tests Run OSX x64 release leg has no log kept:

Not sure were to report that, anyway don't think its related, merging
