[RFC PATCH 01/16] kasan: mark kasan_(hw_)tags_enabled() __always_inline

[Ada Couprie Diaz]

`kasan_hw_tags_enabled()` and `kasan_tags_enabled()` are marked inline,
except `kasan_enabled()` with `CONFIG_KASAN_HW_TAGS`,
which is marked `__always_inline`.

Those functions are called in the arm64 alternative callback
`kasan_hw_tags_enable()`, which requires them to be inlined to avoid
being instrumented and safe for patching.

For consistency between the four declarations and to make the arm64
alternative callback safe, mark them `__always_inline`.
