Subject: Introduce function ecm_install_configured_file

Summary:
This, as the name suggests, configures a file and installs it.

It's not very complicated but it's a repeated pattern in plasma that
gets quite messy dealing with temporary files.

Test Plan: Used in a project

+# ECMConfiguredInstall
+# --------------------
+#
+# Takes a list of files, runs configure_file on each and installs the resultant configured files in the given location.
+#
+# Any suffix of ".in" in the passed file names wil be stripped from the file name at the installed location.
+#
+# ::
+#
+#   ecm_install_configured_files(
+#       INPUT <file> [<file2> [...]]
+#       DESTINATION <INSTALL_DIRECTORY>
+#       [COPYONLY]
+#       [ESCAPE_QUOTES]
+#       [@ONLY]
+#       [COMPONENT <component>])
+#
+# Example usage:
+#
+# .. code-block:: cmake
+#
+#   ecm_install_configured_files(INPUT foo.txt.in DESTINATION ${KDE_INSTALL_DATADIR} @ONLY)
+#
+# This wil install the file as foo.txt with any cmake variable replacements made into the data directory.
