In comparison result, to indicate it's a delta value, we add `+` in
front of positive values. For unchanged attributes, it's still
shown as `0'.

Previously we set loglevel >= WARNING printed to stderr and
loglevel < WARNING printed to stdout. To be more flexible, we
replace this `WARNING` value with an argument: split_level and leave
`WARNING` as default split_level if not set.

When '--show-all' is enabled, all the objects will be displayed in
comparison result no matter if there is code size change or not.

It makes sense to display code size changes if a file has been
removed in our library. With this commit we track old objects as
well. If a file is not present in the new Git revision,
we display -old_size in the new_size column. The size change is
marked as `Removed` to indicate the file has been removed.

The result format for code size comparison is:
filename new(text) new(data) change(text) change(data)
yyy.o xxx xxx xx xx
The numbers followed are in bytes.

Percentage is not a useful number when looking at code size changes.
Since it depends on the base of the code size. It might give
misleading information by simply looking at the numbers.

If we use option --stdout, the logging level is set as
logging.ERROR. But --verbose is able to overwrite logging level as
logging.INFO if we want to display intermediate log in the process
of code size comparison.

If we output comparison result into sys.stdout, it will print an
extra line to show information we used for code size comparison in
detail. This would be helpful if we copy & paste code size changes
in Github comment.

This commit changes how to infer make command. Although we haven't
supported to pass more options in command line, this is the
preparation work to support those features.

The option --markdown supports to only show the files that
have changed in a markdown table between two commits.

Previously we used dec(total) as comparison result of code size
measurement. However, it's not accurate because dec(total) is
the sum of text, data and bss. Now we show text,data instead
since those are sections we care about in code size perspective
specifically for TF-M.

For time being, code_size_compare.py only supports `size`. This
commit builds up foundation to extend code size measurement with
other tools.

CodeSizeCalculator is aimed to calculate code size based on a Git
revision and code size measurement tool. The output of code size is
in utf-8 encoding.

This commit splits CodeSizeBase as a separate class to prepare a
parser as CodeSizeGenerator. The benefit is we can extend the tool
of code size measurement in order to generate more types of code
size record.
