Add Complex Types to What's New in EF8

So also my comments on the blog post, most of which are probably relevant here too.

I wrote a section on the Math improvements in RC1 if you want to add it to this (and possibly the blog post) for tomorrow. (If not, I'll send a separate PR)

Enhancements to Math

Generic math interfaces were introduced in .NET 7. Concrete types like double and float implemented these interfaces adding new APIs mirroring the existing functionality of Math and MathF.

EF Core 8 translates calls to these generic math APIs in LINQ using providers' existing SQL translations for Math and MathF. This means you're now free to choose between calls either like Math.Sin or double.Sin in your EF queries.

We worked with the .NET team to add two new generic math methods in .NET 8 that are implemented on double and float. These are also translated to SQL in EF Core 8.

.NET	SQL
DegreesToRadians	RADIANS
RadiansToDegrees	DEGREES

Finally, we worked with Eric Sink in the SQLitePCLRaw project to enable the SQLite math functions in their builds of the native SQLite library. This includes the native library you get by default when you install the EF Core SQLite provider. This enables several new SQL translations in LINQ.

.NET	SQLite
DegreesToRadians	radians
RadiansToDegrees	degrees
Acos	acos
Acosh	acosh
Asin	asin
Asinh	asinh
Atan	atan
Atan2	atan2
Atanh	atanh
Ceiling	ceiling
Cos	cos
Cosh	cosh
Exp	exp
Floor	floor
Log	ln or log
Log2	log2
Log10	log10
Pow	pow
Sign	sign
Sin	sin
Sinh	sinh
Sqrt	sqrt
Tan	tan
Tanh	tanh
Truncate	trunc

@bricelam Thanks! I've added it here, but I'll leave the blog post focused on complex types.
