Kernel Heap Hardening: use bitmaps on all off-page pools. This migrates 29
MI pools on amd64 from linked lists to bitmaps, which have higher security
properties.
Then, change the computation of the size of the PH pools: take into account
the bitmap area available by default in the ph_u2 union, and don't go with
&phpool[>0] if &phpool[0] already has enough space to embed a bitmap.
The pools that are migrated in this change all use bitmaps small enough to
fit in &phpool[0], therefore there is no increase in memory consumption.

Revert r1.254, put back || for KASAN, some destructors like lwp_dtor()
caused false positives. Needs more work.
