IDLE: Stop reusing built-in names as parameters

[terryjreedy]

Some idlelib functions use built-in names such as 'object', 'dict', and 'type' as function parameter names. As a result, these parameter names are mistakenly highlighted as builtin names. Unless a parameter name is used as a keyword in any call of the function, changing a parameter name within a function should cause no problems.

The easiest name change is to append '_'. That is what I have done so far to get 'object_' and 'dict_' in my b_ins branch.
EDIT: In appropriate places, I prefixed 'g' or 'l', for 'global or 'local', to 'dict'.

Dependency of #87179

I am deferring replacements of 'type' to another issue (currently draft). It has at least as many hits as 'dict' and 'object' combined, and many are argument names in non-idlelib modules. Am closing this and the linked master issue.
