feat(lua)!: add stricter vim.tbl_islist() and rename old one to vim.tbl_isarray() (#16440)

feat(lua)!: add stricter vim.tbl_islist(), rename vim.tbl_isarray()

Problem: `vim.tbl_islist` allows gaps in tables with integer keys
("arrays").

Solution: Rename `vim.tbl_islist` to `vim.tbl_isarray`, add new
`vim.tbl.islist` that checks for consecutive integer keys that start
from 1.
