fix(core/vm): trace before memory expansion #31074

[gzliudan]

Proposed changes

Move opcode tracing out of the dynamic gas branch so tracing always runs before memory expansion. Keep memory resizing in one place to match the upstream interpreter flow.

Pull request overview

This PR adjusts the EVM interpreter loop in core/vm to make tracer hook invocation flow match upstream more closely by moving opcode tracing out of the dynamicGas branch while keeping memory resizing centralized.

Changes:

• Hoists memorySize calculation state outside the dynamicGas block.
• Invokes OnGasChange/OnOpcode tracing in a single unified location.
• Performs mem.Resize(memorySize) in one place after tracing, preserving “trace before expansion” ordering.
