Define a platform-agnostic NET preprocessor symbol

See original GitHub issue

Is your feature request related to a problem? Please describe.

Before .Net 6 days, if I wanted to multitarget to different platforms and split code between them, I could do it with:

#if NETSTANDARD - platform-agnostic code (usually throw new PlatformNotSupported or something)
#if ANDROID - platform-spesific implementation

Now, if I target net6.0;net6.0-android;net6.0-ios, I can still do #if ANDROID (or #if NET6_0_ANDROID_OR_GREATER), but there’s no symbol to check that current TFM is net6.0 (platform-agnostic) like NETSTANDARD, since both NET and NET6_0 are also defined in platform-spesific TFMs.

Describe the solution you’d like

Define a new preprocessor symbol that would indicate platform-agnostic TMF

Workaround

<PropertyGroup Condition=" !$(TargetFramework.Contains('-')) ">
    <DefineConstants>$(DefineConstants);NETSTANDARD</DefineConstants>
</PropertyGroup>

As a design note, not all .NET SDK languages support partial classes (and as a result the multiple files with platform-specific code in each pattern), and so they would be using code like the samples @maxkoshevoi put forth. For that reason having a symbol could help cut down on the noise in a file. What about NET_ANY, keeping in line with the NET_<OS Platform> pattern so far?

Maybe the opposite is fine too?

Define NET_PLATFORM only on the platforms so if I wat a net6.0 only, then I do !NET_PLATFORM
