[fix-finder] Remove #region/#endregion directives from Android.Runtime.XmlReaderPullParser

[github-actions]

Problem

The repository style guide explicitly forbids #region / #endregion directives ("Do NOT use #region or #endregion"), but src/Mono.Android/Android.Runtime/XmlReaderPullParser.cs still contains 3 #region blocks (6 directive lines). They violate the coding conventions. Removing them is a purely cosmetic change with no effect on behavior, public API, or generated IL — #region/#endregion are preprocessor directives that the C# compiler ignores.

Location

• File(s): src/Mono.Android/Android.Runtime/XmlReaderPullParser.cs
• Line(s): the 6 directive lines belonging to these 3 region pairs:
  • #region IXmlResourceParser implementation (line 31) ... #endregion (line 36)
  • #region IAttributeSet implementation (line 38) ... #endregion (line 124)
  • #region IXmlPullParser implementation (line 148) ... #endregion (line 484)

Current Code

Example (the first, compact block):

		#region IXmlResourceParser implementation
		public void Close ()
		{
			r.Close ();
		}
		#endregion

Suggested Fix

Each of these region names carries useful information — it labels which interface's members follow. Per the repo convention for removing regions, preserve the useful name as a single // comment on the line that held the #region directive, and delete the matching #endregion line. Keep the tab indentation and all code between the directives exactly as-is; do not reflow or re-indent anything else.

Apply exactly these six edits:

Line	Current	New
31	#region IXmlResourceParser implementation	// IXmlResourceParser implementation
36	#endregion	(delete the line)
38	#region IAttributeSet implementation	// IAttributeSet implementation
124	#endregion	(delete the line)
148	#region IXmlPullParser implementation	// IXmlPullParser implementation
484	#endregion	(delete the line)

(The #region lines are indented with two tabs; keep the same indentation on the replacement // comments.)

Guidelines

• Follow .editorconfig / Mono style; touch nothing other than the directive lines.
• Keep the change minimal — no unrelated formatting or blank-line churn.
• Do not delete or modify any members; only the preprocessor directives.
• This is a comment-only change and introduces no new APIs, so it compiles against every target framework of Mono.Android.

Acceptance Criteria

• The 3 #region ... implementation lines are converted to // ... implementation comments (indentation preserved)
• The 3 matching #endregion lines are removed
• No other lines in the file changed (no re-indentation or blank-line churn)
• grep -nE "#region|#endregion" src/Mono.Android/Android.Runtime/XmlReaderPullParser.cs returns nothing
• All tests pass
• No new warnings introduced
