JS: establish single source of truth for symbols

In pursuit of: #22736.

This MR moves ad-hoc symbols used throughout the js backend into a
single symbols file. Why? First, this cleans up the code by removing
ad-hoc strings created on the fly and therefore makes the code more
maintainable. Second, it makes it much easier to eventually type these
identifiers.

rts: replace ad-hoc MYTASK_USE_TLV with proper CC_SUPPORTS_TLS

This patch replaces the ad-hoc `MYTASK_USE_TLV` with the
`CC_SUPPORTS_TLS` macro. If TLS support is detected by autoconf, then
we should use that for managing `myTask` in the threaded RTS.

Unicode: adding compact version of GeneralCategory

The following features are applied:
1. Lookup code like Cmm-switches (draft implementation proposed by Sylvain Henry @hsyl20)
2. Nested ifs (logarithmic search vs linear search) (the idea proposed by Sylvain Henry @hsyl20)
3. More compact representation via variable encoding by Huffman
