feat(cpp): Add <Leader>lw keymap to switch between source and header

[rameshsanth]

lw to sWitch between source and header.

"w" isn't assigned to any other key currently.

📑 Description

ℹ Additional Information

Caveat: The keybinding will stay for all LSP although only Clangd supports it. Ideally the keybinding should appear only for buffers Clangd is attached.

Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Proper usage of opts table rather than setting things up with the config function.

If you know the trick to fix make the key map only to C/C++ files, let me know. Otherwise its a minor hassle

We'll have to fix this.

@rameshsanth I'm pretty sure we have the logic for it somewhere in astrocommunity. :)

Marking this as a draft until we fix it.

IMHO, this is not a major issue. There are several key maps that don't apply for every buffer. However it's still loaded and available in vim.
When you get use this short cut on a non CPP file you see this notification.

We should add an autocmd for cleaning up.
For semantic token, we've used this before:

vim.api.nvim_create_autocmd("lspattach", {
  callback = function(args)
    local client = vim.lsp.get_client_by_id(args.data.client_id)
    client.server_capabilities.semantictokensprovider = nil
  end

Should use same logic, just with the astrocore functionality instead.

@rameshsanth Can you test to see if this works as expected now? :)

Issues resolved, now just waiting to hear back from user
