Make console output encoding support all languages

[GangWang01]

Fixes #9694

Context

For console logger, the message is not readable for some languages such as Korean if the system code page is not UTF-8.

Changes Made

Set console output encoding to UTF-8 to support all languages on OSes that support UTF-8.

• On Core unconditionally set the encoding
• On Full framework set the encoding if the OS system locale is non-English.

Testing

Test the fix with msbuild task Message/Warning that contains Chinese/Korean/Japanese using the following cases.

• dotnet build on OS with English locale
• msbuild.exe on OS with English locale (this requires set the env var DOTNET_CLI_UI_LANGUAGE)
• dotnet build on OS with Chinese locale
• msbuild.exe on OS with Chinese locale

Notes

FYI - https://devdiv.visualstudio.com/DevDiv/_workitems/edit/1985518 - We should guard the calls setting the Console properties (OutputEncoding/InpuitEncoding) with try-catch
