Jonathan Brouwer 0cd8de3843 Rollup merge of #153049 - Darksonn:kasan-sw-tags, r=fmease

Add `-Zsanitize=kernel-hwaddress`

The Linux kernel has a config option called `CONFIG_KASAN_SW_TAGS`  that enables `-fsanitize=kernel-hwaddress`. This is not supported by Rust.

One slightly awkward detail is that `#[sanitize(address = "off")]` applies to both `-Zsanitize=address` and `-Zsanitize=kernel-address`. Probably it was done this way because both are the same LLVM pass. I replicated this logic here for hwaddress, but it might be undesirable.

Note that `#[sanitize(kernel_hwaddress = "off")]` could be supported as an annotation on statics, but since it's also missing for `#[sanitize(hwaddress = "off")]`, I did not add it.
