[release/6.0-rc2] [wasm][debugger] Reusing buffer to avoid allocate every debugger message

[github-actions]

Backport of #59480 to release/6.0-rc2

/cc @thaystg

Customer Impact

Reuse the buffer will speed up the debugger experience avoiding allocate and deallocate.

Testing

Ran the unit tests

Risk

No risk, it's reusing buffer as it was doing before, but it's correctly allocating a buffer to reuse.
