Jannis Harder 0f13b55173 Liberty file caching with new `libcache` command 
This adds optional in-memory caching of parsed liberty files to speed up
flows that repeatedly parse the same liberty files. To avoid increasing
the memory overhead by default, the caching is disabled by default. The
caching can be controlled globally or on a per path basis using the new
`libcache` command, which also allows purging cached data.

Sean Luchen 4610889d27 Fix two parsing bugs that were causing private regression tests to fail. 
These were introduced by 0a6d9f4.
1) While in a paren "(", don't error on newline.
2) Don't parse an extra token when parsing vector ranges. Let the caller parse the next token as necessary.

Jannis Harder bc01468c75 read_liberty: Faster std::string construction in the liberty lexer 
This extends the `LibertyInputStream` added in the previous commit to
allow arbitrary lookahead. Then this uses the lookahead to find the
total length of the token within the input buffer, instead of consuming
the token byte by byte while appending to a std::string. Constructing
the std::string with the total length is known avoids any reallocations
from growing std::string's buffer.

Jannis Harder 119e998f12 read_liberty: Faster input handling for the liberty lexer 
The lexer for liberty files was using istream's `get` and `unget` which
are notorious for bad performance and that showed up during profiling.

This replaces the direct `istream` use with a custom LibertyInputStream
that does its own buffering to provide `get` and `unget` that behave the
same way but are implemented with a fast path that is easy to inline and
optimize.

Sean Luchen ac1033ecd5 Factor parse_vector_range out into its own function. 
This also fixes the parsing a bit. It was consuming 1 fewer token than
required.

Makefile: Test yosys git status in check-git-abc 
As in #4986, `check-git-abc` is misleading if Yosys itself isn't a git repository.
So check `git status` before suggesting `git` based solutions, providing alternative suggestions for using ABCEXTERNAL (which bypasses `check-git-abc`), or downloading release tar (noting that the 'Source code' archives won't work, which is probably how they ended up in this situtation).
