6165: Closes #6162: Provide API to speculatively create engine session r=pocmo a=csadilek

See https://github.com/mozilla-mobile/android-components/issues/6162#issuecomment-594093161

.

Another advantage of decoupling this from `speculativeConnect` is that we can also handle private sessions. Applied to all 3 engine variants.

6181: Closes #6180: Update browser-engine-gecko to GeckoView 74 RC2. r=jonalmeida a=pocmo

The actual merge day is next week. But we do already have a stable RC build for GeckoView 74 and therefore would like to update `browser-engine-gecko` already to ship it with Focus. `browser-engine-beta` and `browser-engine-nightly` will be updated next week after merge day.

6170: On memory pressure close engine sessions and keep state for restoring later. r=csadilek a=pocmo

Unfortunately the implementation for this needs to live in SessionManager as long as it keeps
references to EngineSession instances and thumbnails. Therefore we determine what to trim in
SessionManager and notify BrowserStore to perform the same changes.

Hopefully in a not to distant future we can move that to BrowserStore.

Closes #5933.

6153: Closes #6145: Do not invoke close callback on start r=rocketsroger a=jonalmeida

In the tabs tray Flow, `ifChanged` is invoked because the initial state starts with `null` and that in turn invokes the close tabs callback.

We also need to pass the initial filter of tabs from the feature to satisfy changes on the app's side that we need to use here.

6172: Manual GV Nightly upgrade to 75.0.20200304084140 r=Amejia481 a=csadilek

Fixes breaking changes for web ext. APIs. I will address the deprecation of the tab delegate later today as part of https://github.com/mozilla-mobile/android-components/issues/4965

 which we can fix with this.

6151: Closes #6018: Do not load url during link if session is restored r=pocmo,csadilek a=psymoon

The potential pitfall of this patch is we are assuming `geckoSession.restoreState()` would always be successful. Perhaps we could have a follow-up for GV to provide us a callback for when `restoreState()` is completed with a status? 🤔
