Justin M. Keyes 55d3d1bbeb backport: test(lsp): extract buf/util parts from lsp_spec.lua (#39170)
test(lsp): extract buf/util parts from lsp_spec.lua

Problem:
`test/functional/plugin/lsp_spec.lua` had grown into a large catch-all file that mixed core LSP client lifecycle coverage, `vim.lsp.buf.*` behavior, and `vim.lsp.util.*` behavior in one place.

Solution:
Split the large tests into more focused test files without changing test coverage or intended behavior.

After this change, `lsp_spec.lua` is more focused on core LSP client/config/dynamic-registration behavior.
