feat(eval): add reg_recorded()
This function is used the get the last recorded register.
style(Recording): rename handler to match suggestions
fix(RecordingLeave): send autocommand earlier
This makes the autocommand fire just before setting reg_recorded to
reg_recording, this way we clearly show that we are actually just before
actually quitting the recording mode.
Problem:
Since 2f06413dfb#13042, "ESC+c" sequence is treated as "ESC c"
instead of "M-c" (ALT/META+c) when not mapped, aka "fallthrough"
behavior. But "isolated" (non-ALT/META) mappings to ESC and c were not
resolved. This behavior is especially confusing for the TUI.
Solution:
Resolve isolated ESC, c mappings when there is no M-c mapping.
Change ins_char_typebuf() to escape CSI, K_SPECIAL.

Fix was already applied in 5f144efefa#15688,
but this commit adds another dimension to the test.
Test correctly fails after reverting 5f144efefa.
ref #15288
Problem
- `redir_exec` is obsolete, but it keeps getting used in new tests
because people copy existing tests.
- Disadvantages of `redir_exec`:
- Captures extra junk before the actual error/message that we _want_ to test.
- Does not fail on error, unlike e.g. `command()`.
Solution
- Use new functions like `nvim_exec` and `pcall_err`.
Problem:
Subdirectories like "visual", "insert", "normal" encourage people to
separate *related* tests for no good reason. Typically the _mode_ is
not the relevant topic of a test (and when it is, _then_ create
an appropriate describe() or it()).
Solution:
- Delete the various `test/functional/<mode>/` subdirectories, move
their tests to more meaningful topics.
- Rename `…/normal/` to `…/editor/`.
- Move or merge `…/visual/*` and `…/insert/*` tests into here where
appropriate.
- Rename `…/eval/` to `…/vimscript/`.
- Move `…/viml/*` into here also.
* test(reorg): insert/* => editor/mode_insert_spec.lua
* test(reorg): cmdline/* => editor/mode_cmdline_spec.lua
* test(reorg): eval core tests => eval_spec.lua
