### Problem description
In previous versions of ImHex, all tool windows were implemented as
static popups fixed in the upper left position of the hex view. This PR
refactors all tool popups to use floating windows that can be dragged
around by the user, or closed with a dedicated close button on the title
bar. These popup also support a stylable transparency when the user is
not hovering their mouse over the window.
### Implementation description
I rewrote the logic in `ViewHexEditor::drawPopup()` to use a custom
`ImGuiExt::BeginHoveringPopup` function for rendering the popup windows.
This new function is an almost exact replica of the built-in
`ImGui::BeginPopupModal`, except it does also displays the default
window title bar with a close button.
A second custom function, `ImGuiExt::PopupTitleBarButton` was also added
for rendering small icon-based buttons into the title bar of the parent
popup window. This new function was used to implement an optional
"Pinning" feature that individual popup implementations can specify. If
a window is pinned, it won't close automatically when its main action is
executed. For example, the "Select" button on the Select dialog will
close the popup by default, unless the window is pinned.

### Additional things
- When the user stops hovering their mouse over a popup window, it
becomes semi-transparent, making it easier to see the content behind it
- This PR also introduces the `styles.imhex.popup-alpha` style, making
the transparency effect configurable, including the ability to disable
the effect completely by setting `popup-alpha` to `1.0`.
- Fixed a bug that caused some popup windows to ignore the Enter and the
KeypadEnter keys. With this PR, all tool windows will execute their main
action when the user presses either one of the two Enter keys, and will
also close automatically unless the window is pinned.
### Possible changes and improvements
- Should the transparency effect be disabled if a window is pinned?
- Should the transparency factor be modifiable on the Settings/Interface
page?
- A keyboard shortcut could be added for quickly pinning / unpinning the
current window.
- Can the pin icon stay on the left, or should it be moved next to the
close button, with a similar circular background?

I just realized one feature request existed about this tool and have
added a comment to it referring this pr. Errors and additions are
described in the fork commit already. I'm not sure if I should repeat
them here again. I have tested the changes thoroughly, but it is always
possible some fringe case was not tested and is incorrect. The tests
were done using the many similar online calculators for IEEE 754
floating point formats.
IEEE 745 floating point tool redesign modeled after 'float toy' web app
(http://evanw.github.io/float-toy/)
Streamlined output using colors and compact layout which can be further
simplified.
Chosen display mode (detailed or simplified) is automatically saved and
set on new sessions.
Edit the binary bits, the integer hexadecimal or the floating point
decimal values and the entire app will update with the change.
Supports the main IEEE745 standard formats (half, single and double
precision) together with custom formats of size <= 64 bits.
Each format choice uses and displays the number of significant decimal
digits defined by the mantissa size.
Added labels to identify the location of each bit box inside the binary
representation.
Satisfies round trip / idempotent (reproducing) conversion property
Added theme colors, radio buttons for display mode and a clear button
that resets the tool.
Removed previously and incorrectly added locale translation to various
labels and languages
Attempted to adhere to code style formatting using existing code as
example.
An effort was made to use preferred variable types and functions from
std namespace when appropriate.
Attempted to document code using comments.
Not implemented / left to complete at an later time
Arbitrary width and precision formats.
Extended precision formats.
Shortest string property.
hexadecimal floating point display and conversions.
