[release-branch.go1.16] runtime: set iOS addr space to 40 bits with incremental pagealloc

In iOS <14, the address space is strictly limited to 8 GiB, or 33 bits.
As a result, the page allocator also assumes all heap memory lives in
this region. This is especially necessary because the page allocator has
a PROT_NONE mapping proportional to the size of the usable address
space, so this keeps that mapping very small.

However starting with iOS 14, this restriction is relaxed, and mmap may
start returning addresses outside of the <14 range. Today this means
that in iOS 14 and later, users experience an error in the page
allocator when a heap arena is mapped outside of the old range.

This change increases the ios/arm64 heapAddrBits to 40 while
simultaneously making ios/arm64 use the 64-bit pagealloc implementation
(with reservations and incremental mapping) to accommodate both iOS
versions <14 and 14+.

Once iOS <14 is deprecated, we can remove these exceptions and treat
ios/arm64 like any other arm64 platform.

This change also makes the BaseChunkIdx expression a little bit easier
to read, while we're here.

For #46860.
Fixes #48115.

[release-branch.go1.16] runtime/race: rebuild darwin syso to work around macOS 12 malloc reserved address

On macOS 12 a new malloc implementation (nano) is used by default,
and apparently it reserves address range
0x600000000000-0x600020000000, which conflicts with the address
range that TSAN uses for Go. Work around the issue by changing the
address range slightly.

The actual change is made on LLVM at https://reviews.llvm.org/D114825 .
This CL includes syso's built with the patch applied.

The syso in 1.16 was identical to the syso before the equivalent fix
on the main branch, so the back-ported syso is identical to the fixed
syso on the main branch.

Fixes #50072.
Updates #49138.
