[roll third_party/pigweed] pw_build: GN template to evaluate expressions in a file

Pigweed's GN build wraps all invocations of a Python script with a
Python runner. One of the runner's main purposes is to determine the
binary outputs of GN libraries and executables, as this information
is not available through GN itself.

Sometimes, it is cumbersome or unfeasible to pass information to a
script through its command line arguments. Instead, the necessary
data is often written to a file for the script to parse. However,
doing so from within GN bypasses Pigweed's Python runner binary
resolution. `bloat.py` is an example of this -- it needed to import
and run the resolution logic itself.

This adds a template which runs GN binary resolution on files, enabling
the above use case more generally through the build system.
