Improve the fsPromises readFile performance
by allocating only one buffer, when size is known,
increase the size of the readbuffer chunks,
and dont read more data if size bytes have been read.
Also moves constants to internal/fs/utils.

This PR is backporting the fs readFile promise performance improvements to v14.x, essentially copying these two prs (i wasnt able to cherry-pick, not sure if its my git skills or something else):
#38061 "fs: move constants to internal/fs/utils.js"
#37703 "[v14.x backport] fs: improve fsPromises readFile performance"
