core/vm: 64 bit memory and gas calculations (#19210)

* core/vm: remove function call for stack validation from evm runloop

* core/vm: separate gas  calc into static + dynamic

* core/vm: optimize push1

* core/vm: reuse pooled bigints for ADDRESS, ORIGIN and CALLER

* core/vm: use generic error message for jump/jumpi, to avoid string interpolation

* testdata: fix tests for new error message

* core/vm: use 64-bit memory calculations

* core/vm: fix error in memory calculation

* core/vm: address review concerns

* core/vm: avoid unnecessary use of big.Int:BitLen()
