AL55: Remove build-type-not-none lint
Defining CMAKE_BUILD_TYPE=none
frequently causes debug builds to be
enabled, resulting either in larger packages, or even in slower
applications.
The reason this was added was that we want to make sure our build flags
are being used by the build. According to this merge request, this
is also the case with build types like MinSizeRel
, but they are
prepended. That merge request contains further details and reasoning.
See also this merge request, which moves most packages over to
MinSizeRel
, so a lint that suggests to move it back to 'none' is
counter-productive.
Remove the build-type-not-none linting, as it causes more issues than it solves.
