move build configuration into pyproject.toml

[zacharyburnett]

Description

setuptools now supports the [project] table, which is defined by PEP621.

Additionally, setuptools now supports its own entry in pyproject.toml called [tool.setuptools] (pypa/setuptools#1688, https://setuptools.pypa.io/en/latest/userguide/pyproject_config.html#setuptools-specific-configuration); however, it comes with the following disclaimer:

Support for declaring configurations not standardized by PEP 621 (i.e. the [tool.setuptools] table), is still in beta stage and might change in future releases.

Given this, we can attempt to consolidate the build configuration into a single pyproject.toml file that can possibly be read by other build systems in the future.

copying from the stcal PR:

Now that Python 3.11 includes tomli in built-ins, and given that romancal doesn't currently build C extensions, I am comfortable with readying this for review. flake8 requires its own file, but if we ever move to a different linter in the future (e.g. ruff) we will likely be able to use pyproject.toml for its configuration

If setuptools changes their interface with pyproject.toml it would involve updating the [tool.setuptools] table, i.e. changing the following values:

[tool.setuptools]
zip-safe = false

[tool.setuptools.packages.find]

[tool.setuptools.package-data]
# package_data values are glob patterns relative to each specific subpackage.
'*' = [
    '*.fits',
    '*.txt',
    '*.inc',
    '*.cfg',
    '*.csv',
    '*.yaml',
    '*.json',
    '*.asdf',
]

The [project] table would remain unchanged as it is defined by PEP621.
