Warings/ Errors explanations

For error "global $PAGE cannot be used in block classes. Use $this->page."

I just replaced $PAGE with $this->Page as asked. I suppos that $PAGE is not accessible from within a block plugin.

For error "Package tool_save_attestoodle is not valid"

I replaced the wrong reference to another plugin (probable a plugin name copied from another plugin and forgotten here) by the current one (as in the previous block of code in the same file).

For the warning "Unexpected MOODLE_INTERNAL check"

I suppressed lines that performs this check, where it is indicated. As I understood, this check is supposed to prevent direct call of the php file from outside of the plugin. However, for all files that received this warning, the content is only defining functions or classes, and calling this from outside would not produce anything dangerous things, because a function alone does nothing if it isn't called. Idem for a class, defining a class won't do nothing if these class is not instanciated.

So these warning may indicates that in such situations (check + non dangerous code) performing this MOODLE_INTERNAL check is unuseful. Besides, other files in the plugin that also contains the check but contains instructions that performs something, such as affecting variable, did not received such warning (consequently I didn't suppressed anything in them).
