Add cmake option to specify whether warnings / errors are enabled by default.
...
Currently warnings / errors are enabled by default in debug build.
Otherwise they could be enabled only via environmental variable or
API option call. Add possibility to specify the default during the
build time. This simplifies e.g. integration of the library into
bigger projects as no source changes would be required.

Suppress warning about unnamed struct
...
This prevents MSVC complaining with
warning C4201: nonstandard extension used: nameless struct/union
The struct might seem unnecessary to the occasional reader (it did seem
so to this commit's author), but it is not! It is required to align the
fields to a boundary, which is verified by the test suite. Removing that
"unnecessary" `struct` results in this failure:
1: Test command: mimalloc-test-api
[...]
1: test: malloc-zero... mimalloc: assertion failed: at src/page.c:591, mi_page_init
1: assertion: "!mi_page_has_aligned(page)"
