core/vm, params: refactor chain configuration (#19735)
* params, core/vm: deprecating gastable, part 1
* core/vm, params: deprecate gastable, use both constant and dynamic gas
* core/vm, params: remove gastable, remove copypaste
* core/vm: make use of the chainrules
* interpreter: make tracing count constant+dynamic gas
* core/vm: review concerns (param/method name changes)
* core/vm: make use of chainrules more
