perf(build): Use @rollup/plugin-typescript for es5 builds

[AbhiPrasad]

rollup-plugin-typescript2 is way too slow. Using @rollup/plugin-typescript decreases the build times by 95% as a result.

Confirmed with diff checker that this does not change bundle output value.

Before:

yarn run v1.22.19
$ JS_VERSION=es5 rollup -c rollup.bundle.config.js

src/index.bundle.ts → build...
created build in 27.4s

src/index.bundle.ts → build...
created build in 26.9s

src/index.bundle.ts → build...
created build in 26.5s

src/index.bundle.tracing.ts → build...
created build in 39.7s

src/index.bundle.tracing.ts → build...
created build in 40.2s

src/index.bundle.tracing.ts → build...
created build in 39.6s
✨  Done in 201.25s.

After:

yarn run v1.22.19
$ JS_VERSION=es5 rollup -c rollup.bundle.config.js

src/index.bundle.ts → build...
created build in 2.7s

src/index.bundle.ts → build...
created build in 867ms

src/index.bundle.ts → build...
created build in 794ms

src/index.bundle.tracing.ts → build...
created build in 2s

src/index.bundle.tracing.ts → build...
created build in 1.1s

src/index.bundle.tracing.ts → build...
created build in 1.1s
✨  Done in 9.27s.
