[babel-generator]: jsescOption.numbers does not affect NumericLiterals

[sanex3339]

Bug Report

• I would like to work on a fix!

Current Behavior
Currently, when I set:

{
    jsescOption: {
        numbers: 'hexadecimal'
    }
}

This option has not affects any numbers that @babel/generator is generated.

For example i need the following in the output generated code:

var foo = 0x1;

Expected behavior/code

{
    jsescOption: {
        numbers: 'hexadecimal'
    }
}

This option should affect any numbers that @babel/generator is generated

• @babel/generator version: 7.7.7
• Node/npm version: Node 12

Possible Solution
Looks like here: https://github.com/babel/babel/blob/master/packages/babel-generator/src/generators/types.js#L121
number value should be generated using jsesc like in StringLiteral

Set the options as descrived above.

With these options, all numbers should be generated in hexadecimal view:
0 -> 0x0
