Subject: [PATCH] Make the Compilation mode recognize non-legacy Kotlin/Gradle
 errors

The Compilation mode recognizes Kotlin/Gradle errors but only in the old
format.  The new format, which has been in wide use for about a year, is
not supported.  This patch adds support for the new format.

* etc/compilation.txt:
(symbols): Add a non-legacy Kotlin/Gradle warning and error.
* lisp/progmodes/compile.el:
(compilation-error-regexp-alist-alist): Rename 'gradle-kotlin' to
'gradle-kotlin-legacy' and add 'grade-kotlin' that matches errors and
warnings outputted by non-legacy Kotlin/Gradle.
