bbe787a0af Everywhere: Re-format with clang-format-11 
Compared to version 10 this fixes a bunch of formatting issues, mostly
around structs/classes with attributes like [[gnu::packed]], and
incorrect insertion of spaces in parameter types ("T &"/"T &&").
I also removed a bunch of // clang-format off/on and FIXME comments that
are no longer relevant - on the other hand it tried to destroy a couple of
neatly formatted comments, so I had to add some as well.

e6e4fe4f51 LibGUI: Add 1px of margin to EmojiPickerDialog

d441dec5d8 LibGUI: Make the emojis in the emoji input dialog fit in the window 
GUI::Button has a default min-width of 32, so we have to override that
here in order to squeeze all the emojis into the window.

selection.

412a91d58f LibGfx: Add Gfx::Font::bold_variant() that does a proper font lookup 
We previously had a cached bold variant font in Gfx::Font that was very
haphazardly located by filename pattern. This patches replaces that
mechanism with a proper Gfx::FontDatabase lookup for the same font but
with bold weight (700).

54eeb8ee9a AK: Fix a race condition with WeakPtr<T>::strong_ref and destruction 
Since RefPtr<T> decrements the ref counter to 0 and after that starts
destructing the object, there is a window where the ref count is 0
and the weak references have not been revoked.

Also change WeakLink to be able to obtain a strong reference
concurrently and block revoking instead, which should happen a lot
less often.

186499cc25 LibGfx: Update Painter's bezier curve drawing algorithm. 
The new algorithm is an iterative one with an arbitrary threshold for splitting
curves. It splits curves evenly. This should theoretically be less accurate
than the existing recursive approach, but seems to give subjectively better
results in practice.

be1586850d LibGfx: Started working on TTF font parser. 
I'm planning to make this a minimal-allocation TTF parser. This will
speed up start-up time for applications, but have some overhead for
rasterizing glyphs. Which should be okay, since rasterized glyph bitmaps
should be cached anyway.

This commit just adds the loading of the HEAD table.
