text/template: accept new number syntax
This CL updates text/template's scanner to accept the
new number syntaxes:
- Hexadecimal floating-point values.
- Digit-separating underscores.
- Leading 0b and 0o prefixes.
See golang.org/design/19308-number-literals for background.
For #12711.
For #19308.
For #28493.
For #29008.
