proposal: cmd/link: add wasminitmem and wasmmaxmem params

[gggrafff]

Proposal Details

Hello!

The problem

I am compiling my application to GOOS=wasip1 GOARCH=wasm and I want to control the wasm memory more accurate. wasm-ld provides the following parameters for this:

--initial-memory=<value>    Initial size of the linear memory
--max-memory=<value>        Maximum size of the linear memory

But go tool link doesn't allow me to set these values. And I cannot use the wasm-ld because -linkmode=external requires CGO but CGO doesn't support wasm.

Proposal

I propose to add the initial-memory and max-memory cli-parameters to go tool link

Solving

I think that a solving is not too hard and I wish I could help. I expect that the edit should be to pass a couple of constants from the cli-parameters to the module that is responsible for initial memory and max memory. But I looked into the linker code and didn't find where these values are set. Maybe you can tell me how best to solve this task.
