This change adds a GN template which creates a size report card across
a set of different toolchains. The toolchains are defined in a build
variable, each with an optional linker script and Bloaty config. The
size report template builds a base and diff executable with each of the
toolchains and compares the size difference of each.
Example output for the host target:
simple_bloat_toolchain
