SyncIt21 e4029ed9cd More code compression for reagent holder (#79796)
## About The Pull Request
Part 2 of #79686 where we trim down the size of `holder.dm` even further
and in the process give some procs more advanced features as they get
merged with their counterparts.

**1. Removes & merges `get_multiple_reagent_amounts()` proc with
`get_reagent_amount()`**
The proc `get_multiple_reagent_amounts()` was only used by bio generator
and 1 other item with its only use being finding the sum of all reagents
present in the list returned by
`typesof(datum/reagent/consumable/nutrient)`. Currently the approach is
very inefficient because.
- `typesof()` is an expensive call which returns a long list of reagents
- `get_multiple_reagent_amounts()` would then use 2 nested for loops.
One to loop over every reagent in this holder & another inner for loop
to loop over every reagent returned by `typesof()` operator so the time
complexity of this proc is overall multiplicative which in lamen terms
means "Bad"

We can replicate the same behaviour of `typesof()` by using the
`type2parent()` proc and 1 more direct type check to get the exact same
behaviour but with much faster results, therefore reducing overall code

**2. Removes & merges `get_reagent()` proc with `has_reagent()`**
The proc `has_reagent()` is way more advanced than `get_reagent()` with
arguments requesting for a specific amount, metabolization and now even
has a new argument i.e. `chemical flag`. `has_reagent()` has always
returned the reagent reference directly and not a simple TRUE/FALSE so
it is a perfect replacement for `get_reagent()`, therefore reducing
overall code

**3. Removes & merges `has_chemical_flag()` proc with `has_reagent()`**
The proc `has_reagent()` can now look for a specific reagent with a
specific chemical flag as well as mentioned above thus it can replace
`has_chemical_flag()` therefore reducing overall code
