📄 Description

This PR adds an environment option to ignore free memory size checks: OLLAMA_IGNORE_MEMSIZE - it still prints the warning but allows the program to continue (and crash if the allocation fails down the line).

This is a workaround for #5700 and other cases, where high cache usage would make the naive check model_size > (vram_size + sys_free_mem + sys_free_swap) raise a false positive; fully detecting and taking into account e.g. ZFS cache usage would require much bigger changes that are potentially out of scope for this project.

If e.g. other variable name is preferred I'll be happy to adjust it.
Additionally, as I haven't worked with Golang before, all suggestions on improving the code are very welcome - though hopefully the changes are trivial enough to not require too many revisions.
