Fixes focus and blur management when `page.locator(…).focus()` and `page.locator(…).type(…)` are used which was regressed by 7a5b070 (#13510).
#13510 relied on an implicit assumption that this (conditional) [`blur`](7a5b070e95/packages/playwright-core/src/server/injected/injectedScript.ts (L672)) call would always be followed by a call that resulted in a newly focused element via this [`focus`](7a5b070e95/packages/playwright-core/src/server/injected/injectedScript.ts (L674)) call.
However, some elements are [not focusable](https://html.spec.whatwg.org/multipage/interaction.html#focusable-area), so we were blurring incorrectly, and losing focus that we should have maintained.
Two regression tests were added that pass on the commit prior to 7a5b070e95 (and match manual testing/expectations):
* `page.locator(…).focus()`: _keeps focus on element when attempting to focus a non-focusable element_
* `page.locator(…).type(…)`: _should type repeatedly in input in shadow dom_
Additionally, a third test (_should type repeatedly in input in shadow dom_) was added to check the invariant from #13510 that states:
> This affects [contenteditable] elements, but not input elements.
and allows us to introduce the targeted fix (contenteditble check before blur) without breaking FF again.
And _should type repeatedly in contenteditable in shadow dom with nested elements_ was added to ensure the above fix works with nest contenteditble detection.
Fixes#14254.
It turns out that we can only bootstrap Firefox toolchains
from latest commits.
So in case of a full build, we have to fetch latest commit
from `master`, bootstrap from it, and then build the commit we'd like.
This PR fixes the following error message in WPE:
```
[pid=506430][err] (MiniBrowser:506435): GLib-GObject-CRITICAL **: 11:47:23.538: g_object_new_is_valid_property: object class 'WebKitWebContext' has no property named 'process-swap-on-cross-site-navigation-enabled' +0ms
```
Our changes to WPE port that added support for the parameter were removed in 5a3fae4c5a as PSON is enabled by default in WPE (see https://bugs.webkit.org/show_bug.cgi?id=240052) and we don't need to set this explicitly in our fork.

OverridenGeolocationProvider can be destroyed after BrowserContext. Since the provider is owned by WebGeolocationManagerProxy we now store weak pointer to it in the browser context.

Instead of checking repository for the existance of a commit sha,
we should make sure that our remote branch has the commit.
Otherwise, the `export.sh` script later on would not work!
