[pkg/ottl] OTTL Converter Function that is able to create a new time.Time type from a string. #22007
Description
Create an OTTL Converter Function(s), probably called Time, that is able to create a new time.Time type from a string. Something similar to https://pkg.go.dev/time#Parse or https://github.com/knz/strtime or https://github.com/itchyny/timefmt-go can be used.
The function should take 2 parameters, a string (represented as a StringGetter) that represents the time and a string (represented as a StringGetter) that represents the format that the time should be parse. We should also support standard names for common formats in the second parameter, like RFC3339 or ISO 8601 that the function would know how to interpret.
