Implementation of PhutilLexer for Python

Summary: This appears to be ~1.5-2.0x faster than pygments on my machine, which isn't as good as I was hoping for but will help. (This is ~330 ms for a 4400-line file I chose at random.)

Test Plan: Loaded a Python paste and saw highlights that approximately (or maybe exactly) match the pygments version.

Fix bugs in python lexer

Summary:
Two things:

- The appearance of \\ or \' or \-followed-by-a-newline in a raw string would improperly end the string
- A disallowed newline in a string would cause an error instead of trying to continue anyway

Test Plan:
Ran it on a file that was failing for me that was something like:

    x = r'\\"'
    # hello there

Allow `Makefile` files to contain tabs.

Summary: Add an entry to the `.editorconfig` file to allow `Makefile` files to contains tabs over spaces. Without this entry, my editor will automatically convert the tabs to spaces (which `make` does not like).

Test Plan: Opened `./support/xhpast/Makefile` and saved it. Verified that spaces weren't converted to tabs.

Exclude some test data from being linted.

Summary: Currently, `arc lint --apply-patches` will patch some files which contain test data, consequently causing unit tests to file. We should either modify the tests so that they can pass linting and unit tests successfully (if possible), or just exclude them from being linted.

Test Plan: Ran `arc lint --apply-patches` and ensured that these files were not patched.
