Option to Show Hex Values of Variables & Enums on Hover (IntelliSense)

Type: LanguageService

Describe the bug

• OS and Version: Win10
• VS Code Version: 1.55.0
• C/C++ Extension Version: 1.3.0-insiders3
• Other extensions you installed (and if the issue persists after disabling them): N/A
• Does this issue involve using SSH remote to run the extension on a remote machine?: No
• A clear and concise description of what the bug is, including information about the workspace (i.e. is the workspace a single project or multiple projects, size of the project, etc). Not a bug. It's a feature.

Steps to reproduce

Expected behavior

Add a workspace/settings option to be able to show the hex values of variables upon hovering over them, using IntelliSense. Likewise have an option for when hovering over enum values. This is especially useful when dealing with enum values that intentionally enumerate over specific hex ranges for things like different protocols' message/arbitration IDs, etc.

Sometimes when I hover over hex enum values, the hex value will flicker in the tooltip before being replaced by a decimal value, so the extension is definitely capable of at least showing hex values "as declared", which is usually more useful behavior than showing their decimal equivalents anyway.

Start by locating the TypeScript LanguageService implementation responsible for IntelliSense hover results and the related tests. Trace how variable and enum values are formatted, then determine where a workspace setting would be read. Done means hover tooltips can optionally preserve hexadecimal values for both variables and enum members, with coverage for the setting and display behavior.
