Introduce CATCH_CONFIG_PREFIX_MESSAGES to only prefix a few logging related macros. (#2544)

* Add missing include for VxWorks build.

std::min is defined in algorithm provides std::min. It appears to be transitively included for most platforms. For VxWorks however this explicit include is required.

* Add option CATCH_CONFIG_PREFIX_MESSAGES to selectively prefix message macros only.

In contrast to CATCH_CONFIG_PREFIX_ALL, this will only prefix the following macros:
I.e. INFO, UNSCOPED_INFO, WARN and CATCH_CAPTURE

This is mainly useful for codebases that use INFO or WARN for their own logging macros.

 ## Prefixing Catch macros
 
-    CATCH_CONFIG_PREFIX_ALL
+    CATCH_CONFIG_PREFIX_ALL       // Prefix all macros with CATCH_
+    CATCH_CONFIG_PREFIX_MESSAGES  // Prefix only INFO, UNSCOPED_INFO, WARN and CAPTURE
 
 To keep test code clean and uncluttered Catch uses short macro names (e.g. ```TEST_CASE``` and ```REQUIRE```). Occasionally these may conflict with identifiers from platform headers or the system under test. In this case the above identifier can be defined. This will cause all the Catch user macros to be prefixed with ```CATCH_``` (e.g. ```CATCH_TEST_CASE``` and ```CATCH_REQUIRE```).
