Fix a consistency bug of ISEQ_COVERAGE [Bug #13305]
There is an invariant that ISEQ_COVERAGE(iseq) must be Qnil if and only
if option->coverage_enabled is false. This invariant was broken by
NODE_PRELUDE which updates option->coverage_enabled but not
ISEQ_COVERAGE(iseq).

[Bug #12628]
This patch introduce many changes.
* Introduce concept of "Block Handler (BH)" to represent
passed blocks.
* move rb_control_frame_t::flag to ep[0] (as a special local
variable). This flags represents not only frame type, but also
env flags such as escaped.
* rename `rb_block_t` to `struct rb_block`.
* Make Proc, Binding and RubyVM::Env objects wb-protected.

All of the strings created here eventually get converted to
fstrings when they are frozen into the iseq. Prepare the
fstring early so we may reduce a one or two objects.
This is a very minor change, mainly for the '<main>' dedupe.

(it is converted to fstring anyways inside rb_iseq_new_with_opt)
* iseq.c (iseqw_s_compile): ditto

* vm.c (Init_VM): ditto, share with with above
* iseq.c (iseqw_s_compile_file): rb_fstring before rb_io_t->pathv
share "<main>" with above
* vm.c (rb_binding_add_dynavars): fstring "<temp>" immediately
