Initial work to get clang building ARM firmware.
Current state:
- Does not work on Windows; no clang toolchain yet.
- Almost all tests pass.
- FreeListHeap tests that don't zero-initilize the buffer fail in qemu
and crash on STM32F429I-DISC1. (pwbug/315)

This adds a non-blocking version of ReadByte() that enables writing, for
example, a superloop that combines custom processing simultaneously with
byte input handling for the RPC subsystem.

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

- Update labels so they use consistent naming. Instead of the
copy-and-pasted `chapter` prefix, name labels with a prefix consistent
with what they point to:
- "module-" for module
- "target-" for targets
- "docs-" for general documentation
- Remove the unnecessary highlight and default-domain directives.
Neither is necessary since the Pigweed docs always specify the
language in code snippets and other directives.

Alters the existing targets to use a boot.cc file instead of the
existing early_boot.c.
The name was updated to reflect the fact that it now contains a
pw_boot_PostMain() hook which is after early boot.
C++ was selected over C to give more language flexibility.

Updates targets/lm3s6965evb-qemu/* and its sys_io counterpart to
match targets/stm32f429i-disc1/* by moving the early boot and
vector tables out of sys_io.

If you make an infinite loop without a break or return, it is infinite.
Probably not intended behavior. :) Present me is disappointed in past me.

Require targets to explicitly import pigweed variable definitions. This
moves out some necessary logic from the BUILDCONFIG.gn file.

This change replaces the implicit overrides of the default GN target
types in BUILDCONFIG.gn with explicit pw_* versions. This is done to
allow Pigweed to build within larger GN projects without modifying their
BUILDCONFIG files.

Adds pw_PreStaticConstructorInit() to allow ARMv7-M targets that use
pw_boot to perform initialization before C++ static constructors are
run. Updates stm32f429i-disc1 to enable FPU before static constructors
so static constructors can safely perform FPU operations if necessary.
