[Feature] Support stringified via tags numeric literals

[MaxGraey]

Examples

const a = u32`0xFF` // same as u32(0xFF), <u32>0xFF, 0xFF as u32
const b = f64`-1e5` // ^
// etc

Motivation

It will allow support non-standard for TypeScript / JavaScript literal formats like hexadecimal floating points:

f64`0x1.2afep+34`
f32`0x1.0-2`

If you allow you to create custom tags, it could also be useful for third-party libraries. Possible examples:

u128`170141183460469231731687303715884105728`;
bigint`10889035741470030830827987437816582766592`;
deg`45`; // may convert to 0.7853981634 radians inplace
min`5`; // may convert to 300000 ms inplace 

For MVP we can implement only tags for builtin types without custom defined tags
