Translate-C changes

[frmdstryr]

This adds/fixes a few things I ran into while translating some MCU headers:

1. Enables warnings by default and adds a flag to disable it
2. Adds support for right shift, add, and sub operations
3. Adds warnings when a macro is not processed
4. Adds a "format" to the AstNodeIntLiteral so hex / octal format can be retained when translating.

For example

#define PERIPH_BASE               (0x40000000UL) /*!< Base address of : AHB/APB Peripherals                                                   */
#define D3_AHB1PERIPH_BASE       (PERIPH_BASE + 0x18020000UL)
#define RCC_BASE              (D3_AHB1PERIPH_BASE + 0x4400UL)

Now translates to

pub const PERIPH_BASE = @as(c_ulong, 0x40000000);
pub const D3_AHB1PERIPH_BASE = PERIPH_BASE + @as(c_ulong, 0x18020000);
pub const RCC_BASE = D3_AHB1PERIPH_BASE + @as(c_ulong, 0x4400);

vs just

pub const PERIPH_BASE = @as(c_ulong, 1073741824);
// The other's are missing

Edit: Broke some stuff... will reopen if I can fix that.

There is a PR incoming where all the translate-c code will be in zig instead of in c++. Please try to use that PR and see if your issue is fixed or wait until the self-hosted translate-c is merged (#3973)

Still doesn't support + in macros but everything else is in there. Thanks for commenting, I'll try to contribute to that PR.
