arm64: kasan: Set TCR_EL1.TBID1 when KASAN_HW_TAGS is enabled

Commit 49b3cf035edc ("kasan: arm64: set TCR_EL1.TBID1 when enabled") set
the TBID1 bit for the KASAN_SW_TAGS configuration, freeing up 8 bits to
be used by PAC. With in-kernel MTE now in mainline, also set this bit
for the KASAN_HW_TAGS configuration.
