[android] update AOT profiles (#6834)

In #6820 Rachel and I noticed that there were quite a few API changes
that made the `.aotprofile`'s for MAUI out of date.

Looking at the [JIT times report][0] for the .NET Podcast app, I saw a
couple we could address:

Total (ms) |  Self (ms) | Method
      2.61 |       2.61 | string:SplitInternal (string,string[],int,System.StringSplitOptions)
      1.57 |       1.57 | System.Number:NumberToString (System.Text.ValueStringBuilder&,System.Number/NumberBuffer&,char,int,System.Globalization.NumberFormatInfo)
      1.52 |       1.52 | System.Number:TryParseInt32IntegerStyle (System.ReadOnlySpan`1<char>,System.Globalization.NumberStyles,System.Globalization.NumberFormatInfo,int&)

I added usage of `string.Split()`, `int.Parse()`, and `int.ToString()`
to `CommonMethods.cs`.
