Refactor C++ entrypoints

Refactor all C++ entrypoint function (those that can be called from
assembly entrypoints) declarations into a new header file. Now all
C++ entrypoint functions have a single declaration, inside a header
that can be included as needed. This removes the need for additional
declarations to be made which, if not type checked, could be
mismatched with the function definition.

A macro is used to declare each entrypoint inside the header but also
allows operations to be done on all C++ entrypoints similar to
assembly entrypoints with its macro in quick_entrypoints_list.h.

Note: linkers, unlike compilers, do not typically type check
function declarations against defintions, e.g: when linking between
two libraries. This can cause mismatches which are not caught when
building and therefore become difficult to debug later.

This patch aims to unify all C++ entrypoint function declarations,
i.e: those C++ functions called from assembly entrypoints.
By doing this any unnecessary and potentially conflicting
declarations can be removed to ensure a single source of truth.
