The "# gn-format disable" comments are no longer necessary. Delete these
comments and reformat with a Vim macro and gn format.

In general toolchains should set values for the builtin arguments
current_cpu and current_os; this configures both the toolchain itself
and everything it builds. Make it so in Pigweed.
If there's a toolchain with current_os = "ios", use the arguments for
Apple's linker.

Add functions to check if a pw::allocator::Block object is valid in the
sense that it's aligned, the prev/next pointer matches with each other,
and poison bytes is not corrupted if enabled. Add functions to crash on
seeing an invalid Block.
Add a gn arg to enable heap poison, with sizeof(void*) before and after
the usable space with a fixed pattern.

The pw_cpu_exception facade is comprised of three parts: the part
implemented by the architecture, and the part implemented by the
application, and some supporting libraries that make it easier to dump
CPU state. Since these are provided independently, the facade has been
split into three facades:
1. entry
2. handler
3. support

Removes floating point printf support from the default ARM toolchain and
makes it into an optional config that isn't added by default (since it
adds ~14KB of flash usage).

Updates pigweed to depend directly on is_host_toolchain provided by the
toolchain. Also adds a toolchain option that controls the extension of
final linked binaries.
