Fixes Issue #4323.
The check to see if a call to configure_file() overwrites the output of
a preceding call should perform the substitution for the output file
before doing the check.
Added tests to ensure the proper behaviour.
It's possible that the configuration data object has components added
conditionally, and that sometimes an empty configuration data object
is passed on purpose.
Instead, we do the substitution and also warn if no tokens were found
that could've been substituted.
Closes https://github.com/mesonbuild/meson/issues/3826
Input files can be in any file encoding, not just utf-8 or isolatin1. Meson
should not make assumptions here and allow for the user to specify the
encoding to use.
This will copy the file to the build directory without trying to read
it or substitute values into it.
Also do this optimization if the configuration_data() object passed to
the `configuration:` kwarg is empty, and print a warning about it.

The added format argument for configure_file allows to specify the kind of
file that is treated. It defaults to 'meson', but can also have the 'cmake'
or 'cmake@' value to treat config.h.in files in the cmake format with #cmakedefine
statements.
The configure_file command raised an exception when an input was specified as a
File, because os.path.join does not take File objects directly. This patch
converts a File object to a string and adjusts the subsequent os.path.join
calls.
The same substitutions and rules as custom_target().
Also generally fix it to actually work when run in a subdir and with
anything other than absolute paths for input and output files.
We now also log a message when configuring files.
Includes tests for all this.
Add support for passing a description to configuration data
setter methods via a 'description' kwarg. The description
string will be used when meson generates the entire configure
file without a template, autoconf-style.
