Removes strict-boolean-expressions because its too noisy

Avoids unneeded `void`s to know if return value is intentionally discarded
Uses `type` imports when possible (avoids unneeded bundling)

This enables basic multi-select support, but commands have not been audited for proper support and may fail completely or corrupt data (try it at your own risk)

Commands run with multi-select will sequentially execute the command for each selected item (assuming each item is of the same type at the active item, e.g. the item the context menu was shown for), unless they are specifically multi-select aware.

Currently only dropping stashes is now multi-select aware.

Removes commit details webview (tab-based)

- adds lit components
- exposes webview in WebviewViewBase
- adds pointer cursor to enabled buttons
- adds custom events support to DOM utility

- Changes request failures to only disconnect the integration for the current session
 - Limits to 5 failed request before disconnecting the integration
 - Avoids disconnect prompt for current session disconnections
 - Adds don't show again to request failure messages
 - Adds integration suspension message w/ don't show again option

* update vscode git api
* force-push for non-HEAD commit & commit widget

Remembers comparison file filtering on filter/refresh
Disallows comparisons with the working tree (e.g. right side)
Disables swap when comparing from the working tree

Adds new in-memory node state storage to views

- adds command palette action

This is an ugly hack, but node-fetch doesn't seem to be able to pass `rejectUnauthorized` through on the request options properly even though we are creating a HTTPS agent with it set

Adds autolink configure command to autolinked issues & prs node

Adds line fading option to heatmap annotation

And separates the existing Gerrit provider to a new GoogleSource one.
