BUG: add missing c_distributions.pxd, enables cython use of random C-API (gh-15463)
xref gh-14778
As pointed out in the comment by @jamesthomasgriffin, we did not include a pxd file to expose the distribution functions documented in the random c-api. This PR adds a c_distributions.pxd file that exposes them.
Squashed commits:
* BUG: add missing c_distributions.pxd to enable cython use of random C-API
* ENH, TST: add npyrandom library like npymath, test cython use of it
* BUG: actually prefix f-string with f
* MAINT: fixes from review, add _bit_generato_bit_generator.pxd
* STY: fixes from review
* BLD: don't use nprandom library for mtrand legacy build
* TST: WindowsPath cannot be used in subprocess's list2cmdline
* MAINT, API: move _bit_generator to bit_generator
* DOC: add release note about moving bit_generator
* DOC, MAINT: fixes from review
* MAINT: redo dtype determination from review
